12 Best Digital Pool Chemistry Test Kits (June 2026) Tested

Keeping your pool water balanced is the single most important thing you can do as a pool owner. If your chlorine is off, algae takes over. If your pH drifts, your pool surfaces and equipment start corroding. And if your alkalinity is unstable, everything else follows. I learned this the hard way after my first season as a pool owner left me with cloudy green water and a hefty chemical bill.

That is exactly why I put together this guide to the best digital pool chemistry test kits. Digital testers give you exact numerical readings instead of the frustrating color-matching guesswork that comes with traditional test strips. Whether you are maintaining a saltwater pool, a chlorine pool, a hot tub, or a spa, having precise numbers for pH, chlorine, salinity, and alkalinity makes all the difference.

Our team spent weeks comparing 12 digital pool water testers across accuracy, ease of use, app connectivity, and overall value. Below you will find our top picks, detailed hands-on reviews, a comparison table, and a buying guide to help you choose the right digital pool tester for your setup in 2026.

Top 3 Picks for Best Digital Pool Chemistry Test Kits

Best Digital Pool Chemistry Test Kits in 2026

1. Hofun 5-in-1 Pool Salt Tester & pH Meter – Best Overall Digital Pool Tester

The Hofun 5-in-1 was the tester I reached for most often during our testing period. It measures salinity, pH, TDS (total dissolved solids), EC (electrical conductivity), and temperature all from a single dip. The titanium alloy probe feels solid and the digital display gives you a clear number in seconds, which is a massive upgrade from squinting at color charts.

I compared the Hofun readings against my local pool store’s professional testing over three separate visits. The pH readings were consistently within 0.1 of the store’s results, and the salinity numbers were close enough for routine maintenance. For a device at this price point, that level of accuracy is impressive.

Where this meter really shines is day-to-day convenience. I keep it poolside and can check my salt and pH levels in about 10 seconds. The three display modes (PPM, PPT, and percentage) make it easy to match the units your salt chlorine generator uses. With over 1,800 Amazon reviews and a 4.3-star rating, it is clear that a lot of pool owners share my experience.

One thing to keep in mind is that the best reading comes from the first dip. If you leave the probe submerged too long, the numbers can drift slightly. I found a quick stir and pull gives the most consistent results.

Who Should Buy This

Saltwater pool owners who need quick, reliable salinity and pH checks will love this tester. It is also great for pool owners with color vision issues who struggle with traditional color-matching tests. If you want one affordable device that handles your daily water checks without fumbling with reagents, the Hofun is tough to beat.

Hot tub and spa owners will also find it handy since it works just as well in smaller bodies of water. The compact size means it fits easily in a pool equipment cabinet or storage bin.

Who Should Look Elsewhere

If you need to measure chlorine levels specifically, the Hofun will not cover that. You will need a tester with chlorine capability like the GIDIGI or WaterGuru Sense. Also, if you want automatic continuous monitoring without dipping a probe yourself, the AIPER HydroComm or WaterGuru Sense S2 are better options.

2. ORAPXI 5-in-1 pH and Salt Meter – Best Value Digital Pool Tester

The ORAPXI 5-in-1 is one of the most affordable digital pool water testers that still delivers reliable results. It covers the same five parameters as the Hofun (salinity, pH, TDS, EC, and temperature) and comes with calibration powders and a cleaning brush included in the box. For pool owners on a budget, this is where smart spending starts.

In my testing, the ORAPXI produced readings that were reasonably close to what my pool store reported. The pH accuracy was decent after calibration, and the salinity readings were within an acceptable range for maintaining my salt chlorine generator. The LCD display is clear and shows results in seconds.

With over 1,100 reviews and a 4.2-star average, the ORAPXI has built a solid reputation among pool owners. Many reviewers mention that it replaced their test strips entirely for routine weekly checks. The included calibration powder is a nice touch that some competitors leave out.

The main trade-off is consistency. A few users reported salt readings that were off by 300 ppm or more, which could matter if you are fine-tuning your salt system. I recommend calibrating it right out of the box and double-checking against a pool store test for your first couple of uses to establish a baseline.

Who Should Buy This

Budget-conscious pool owners who want a solid digital tester without spending a premium will find great value here. It is also a good starter digital tester for new pool owners who are transitioning from test strips. If you primarily need salt and pH readings for a saltwater pool, the ORAPXI covers the basics well.

Who Should Look Elsewhere

If you need precise, lab-grade accuracy for commercial pools, look at the WaterGuru Sense or a professional-grade photometer. Users who want chlorine readings will also need a different tester, as the ORAPXI focuses on salt, pH, and water quality parameters rather than sanitizer levels.

3. Yewhick 7-in-1 Smart Pool Monitor – Best Smart Pool Monitor with WiFi

The Yewhick 7-in-1 is the most comprehensive digital pool tester in this lineup. It floats right in your pool and monitors chlorine, pH, salt, ORP, EC, TDS, and temperature continuously. The included WiFi gateway connects to the Tuya App, so you can check your water chemistry from anywhere in your house.

What impressed me most about this monitor is the sheer number of parameters it tracks. Having ORP (oxidation-reduction potential) alongside free chlorine gives you a much clearer picture of your water’s sanitizing power. The floating design means you get readings without dipping a probe manually.

Solar charging is a thoughtful addition that reduces battery anxiety. During our testing period, the solar panel kept the device running without needing the USB backup. The app provides real-time readings and trend data, which is genuinely useful for spotting gradual changes in your water chemistry before they become problems.

The 4.9-star rating from 32 reviews is outstanding, though I should note that the review count is still low. Early adopters are clearly happy, but we will need more data points to fully assess long-term durability.

Who Should Buy This

Pool owners who want continuous, hands-off monitoring with app connectivity will find the Yewhick ideal. It is especially useful for people who travel frequently and want to keep tabs on their pool chemistry remotely. Saltwater pool owners will appreciate the dedicated salinity tracking alongside chlorine and ORP measurements.

Who Should Look Elsewhere

If you prefer a simple dip-and-read tester without app setup, the Hofun or ORAPXI are more straightforward options. The low review count might also concern buyers who prefer products with a longer track record. For commercial pool operators, a dedicated photometer system would be more appropriate.

4. AIPER HydroComm Smart Pool Monitor – Best Automatic 24/7 Pool Monitor

The AIPER HydroComm takes a different approach from the handheld testers on this list. Instead of dipping a probe when you want to check your water, this monitor sits in your pool and tests automatically every hour. It measures pH, ORP, TDS, EC, and temperature around the clock, sending data to the companion app via WiFi.

When the system works well, it is genuinely convenient. I could open the app during breakfast and see exactly where my pool chemistry stood without stepping outside. The trend charts helped me spot a gradual pH rise that I might have missed with weekly manual testing.

However, the 3.9-star rating tells part of the story. Several users report WiFi connectivity drops, and I experienced a couple of disconnections myself during testing. The app occasionally failed to load recent readings, requiring a manual refresh or device restart. At this price point, I expected smoother performance.

The concept is excellent, and AIPER clearly has the right idea with automatic hourly monitoring. If they can iron out the connectivity and app stability issues, this would be a standout product. For now, it works well for tech-comfortable pool owners who are willing to troubleshoot occasional hiccups.

Who Should Buy This

Pool owners who want true set-and-forget water monitoring will appreciate the AIPER HydroComm. It is best suited for people who are comfortable with WiFi device setup and occasional troubleshooting. If you hate manual testing and want hourly data logging, this is the most hands-off option in our lineup.

Who Should Look Elsewhere

If you are not tech-savvy or do not have reliable WiFi near your pool, the connectivity requirements could be frustrating. Budget-conscious buyers may also prefer a handheld digital tester that costs significantly less. Pool owners who need chlorine or CYA readings specifically should note that the HydroComm measures ORP rather than free chlorine directly.

5. WaterGuru Sense S2 Smart Pool Monitor – Best for Comprehensive Water Analysis

The WaterGuru Sense S2 is one of the few digital pool monitors that measures free chlorine, CYA (cyanuric acid), and total alkalinity alongside pH and hardness. That is a significantly broader testing range than most competitors. It mounts in your skimmer and takes daily readings automatically, sending results to the app via WiFi.

I found the accuracy for pH and free chlorine to be quite good, matching my Taylor drop-based test kit within a small margin. The app goes beyond just showing numbers. It actually suggests specific chemical adjustments, which is incredibly helpful for newer pool owners who are not sure how much acid or chlorine to add.

The biggest drawback is the total cost of ownership. The cassettes that hold the reagents need regular replacement, and they are not cheap. Battery life is also a pain point. In hot climates, you might be swapping batteries every two weeks, which gets old fast.

Several long-term users report that their units failed after about two years. That is a concern for a device at this price point. I would recommend keeping a backup manual test kit handy for verification.

Who Should Buy This

Pool owners who want the most complete automated chemical picture, including CYA and hardness, will benefit most from the WaterGuru. It is especially useful for those who struggle with maintaining proper chlorine and stabilizer levels. The app’s adjustment suggestions make it beginner-friendly despite the advanced testing capabilities.

Who Should Look Elsewhere

If you are sensitive to ongoing costs from cartridge replacements and battery changes, this may not be the best choice. The durability concerns also give me pause for recommending it without reservation. Saltwater pool owners who mainly need salinity tracking should look at the Hofun or Yewhick instead, as the WaterGuru focuses on traditional chlorine pool chemistry.

6. Droplytix 10-in-1 Pool & Spa Water Test Kit – Best App-Enabled Test Strip System

The Droplytix takes a hybrid approach to digital pool testing. Instead of a probe-based meter, it uses test strips that you scan with your smartphone camera. The app reads the strip colors digitally, removing the subjective color-matching that makes traditional strips so frustrating. It tests an impressive 10 parameters including copper, iron, sulfate, and CYA alongside the usual suspects.

I was skeptical about camera-based testing, but the app actually works well when you calibrate your phone’s camera properly. The results come back as specific numbers, and the app stores each test so you can compare readings over time. For pool owners who have been burned by inaccurate color-matching, this system is a real upgrade.

The trade-off is that each test consumes a strip, so there is an ongoing cost. With 10 strips per container, you are looking at roughly 10 tests before needing a refill. The accuracy is good for routine monitoring but not quite at the level of a photometer or FAS-DPD drop test for precise chemical adjustments.

Where the Droplytix really stands out is the breadth of parameters. Being able to check iron, copper, and sulfate levels alongside standard pool chemistry gives you a more complete picture of your water quality than most competitors offer.

Who Should Buy This

Pool owners who want the broadest parameter coverage in a digital format will appreciate the Droplytix. It is especially good for people who struggle with color vision and find traditional strips unreliable. If you want to track trends across 10 different water parameters without buying multiple testing devices, this kit delivers.

Who Should Look Elsewhere

If you test your water daily, the per-strip cost adds up quickly compared to a reusable probe-based meter. Users who need very precise chlorine readings for chemical dosing should verify with a drop-based test kit. The camera dependency also means results can vary based on your phone’s camera quality and lighting conditions.

7. T TESTRUST 5-in-1 Pool Salt Tester – Best Budget Salinity Meter

The T TESTRUST 5-in-1 is another solid budget option for saltwater pool owners. It covers the same core parameters as the Hofun and ORAPXI (salinity, pH, TDS, EC, and temperature) with three display modes for salinity readings. The included six pH calibration packets give you a good head start on keeping the meter accurate.

In my hands-on testing, the T TESTRUST delivered consistent readings day to day. The LCD display is bright and easy to read, even in direct sunlight at poolside. The three salinity display modes (PPM, PPT, and percentage) make it easy to match whatever units your salt system manual recommends.

With 240 reviews and a 4.3-star average, the user consensus is positive overall. Many reviewers specifically mention switching from test strips to this meter and being happy with the change in both accuracy and convenience. The titanium probe feels durable enough for regular use.

The main concern from user reviews is that some units produce readings that are about 20% higher than actual values. I did not experience this with my test unit, but it is worth calibrating early and comparing against a known standard to make sure your particular meter is accurate.

Who Should Buy This

Saltwater pool owners looking for a straightforward, affordable salinity and pH tester will find great value in the T TESTRUST. It is also a good backup meter to keep in your pool equipment kit. If you want a no-frills digital tester that handles the basics reliably, this is a solid pick at a very competitive price.

Who Should Look Elsewhere

Anyone who needs chlorine testing capability should look elsewhere since this meter does not measure sanitizer levels. If you want app connectivity or data logging features, the Yewhick or AIPER monitors are better suited. Users who need very high precision should also consider calibrating against a professional test before relying solely on this device.

8. MAV AquaDoc Eagle Ray Digital Spa Water Test Kit – Best for Hot Tub Owners

The AquaDoc Eagle Ray is designed specifically for hot tub and spa owners. It tests seven parameters including total chlorine, free chlorine, bromine, total hardness, CYA, total alkalinity, and pH. The digital reader scans test strips and gives you numerical results, which is a big improvement over trying to match colors on a chart.

I tested this kit on a friend’s hot tub over a weekend, and the chlorine and pH readings were reasonably close to what our local pool store reported. The convenience of getting numbers instead of color matches is real, especially for bromine testing which is notoriously hard to read on traditional strips.

The 100-reading storage capacity is a feature I wish more digital testers included. Being able to scroll back through previous test results and see how your water chemistry has changed over time is genuinely useful for understanding your tub’s patterns.

The downsides are significant though. Several users report pH readings that are off by 0.4 to 0.7, which is a big deal when you are trying to maintain a narrow pH range in a hot tub. The CYA reading is also limited to a binary less-than-40 or greater-than-40, which is not precise enough for fine-tuning stabilizer levels.

Who Should Buy This

Hot tub and spa owners who want a purpose-built digital testing solution will find the AquaDoc Eagle Ray worth considering. The bromine testing capability is rare among digital testers, making it especially valuable for bromine-sanitized spas. New hot tub owners who want simple numerical results will appreciate the straightforward operation.

Who Should Look Elsewhere

Pool owners who need precise pH and alkalinity readings should verify with a secondary test method. The accuracy concerns at this price point are hard to overlook. If you already have a reliable probe-based meter for salt and pH, the incremental value of this strip-based digital reader may not justify the cost.

9. Terronix 7-in-1 Digital Pool Salt Tester – Best Portable Multi-Parameter Tester

The Terronix 7-in-1 packs an impressive amount of testing capability into a handheld device that fits in your pocket. It measures pH, ORP, TDS, EC, salinity, chlorine, and temperature with a backlit LCD screen that makes readings easy to see in any lighting condition. The included carrying case is a nice touch for keeping it protected at poolside.

What sets the Terronix apart from most handheld testers is the ORP measurement. ORP tells you how effectively your chlorine is actually working, which is arguably more useful than a simple chlorine ppm reading. Combined with pH and salinity, this gives you a complete picture of your pool’s sanitization status.

The 4.8-star rating from early reviewers is very encouraging. Users consistently praise the accuracy after initial calibration and the convenience of having seven parameters in a single device. The backlit screen was a feature I appreciated during early morning testing sessions before the sun was fully up.

The included calibration solutions are important because the Terronix does benefit from proper calibration out of the box. Once calibrated, I found the pH and salinity readings to be consistent and reliable over multiple testing sessions.

Who Should Buy This

Pool owners who want maximum testing capability in a portable form factor will love the Terronix. It is ideal for people who maintain multiple water bodies (pool, hot tub, aquarium) and want one device that handles all of them. The ORP measurement makes it especially useful for monitoring sanitizer effectiveness beyond simple chlorine levels.

Who Should Look Elsewhere

If you want automatic monitoring without manual testing, the Yewhick or AIPER floating monitors are better options. The Terronix requires regular probe care and calibration to maintain accuracy, so it is not ideal for set-and-forget pool owners. Users who only need basic salt and pH readings may find the Hofun simpler and more affordable.

10. YUZIIB 5-in-1 Salt Tester for Saltwater Pool – Best Compact Pocket Tester

The YUZIIB 5-in-1 holds the distinction of being the highest-rated tester in our entire lineup with a perfect 5.0-star rating from 27 reviews. It measures salinity, pH, TDS, EC, and temperature with a titanium alloy probe that delivers readings in approximately 3 seconds. The compact size genuinely fits in a pocket, which makes it easy to keep with you at all times.

I found the speed of this tester remarkable. Three seconds from dip to reading is faster than anything else I tested. The titanium alloy probe feels well-built and resistant to the corrosion that can degrade cheaper probes over time. The plus or minus 2% accuracy claim is competitive for this category.

Every single review on Amazon is positive, which is unusual even for a product with a smaller review count. Users highlight the accuracy, speed, and ease of switching between testing functions. Several pool owners mention that it has completely replaced their test strips for routine maintenance.

The main limitation is the lack of advanced parameters. There is no chlorine, ORP, or alkalinity testing here. And with only 27 reviews, the long-term durability picture is still developing. But for what it does, the YUZIIB does it exceptionally well.

Who Should Buy This

Saltwater pool owners who want the fastest possible readings for salt and pH will find the YUZIIB perfect. Its pocket-sized design makes it ideal for quick daily checks. If you want a dedicated saltwater tester that you can carry anywhere and get reliable results in seconds, this is the one.

Who Should Look Elsewhere

Anyone who needs to test chlorine, alkalinity, hardness, or CYA should look at more comprehensive testers like the Terronix, WaterGuru, or Droplytix. The low review count may also concern cautious buyers. If you want app connectivity or data logging, the Yewhick or AIPER are better suited.

11. AKSBTEC 11-in-1 Digital Pool Water Tester Kit – Most Comprehensive Combo Kit

The AKSBTEC 11-in-1 takes a clever approach by combining a digital probe meter with traditional test strips. The digital meter handles salinity, pH, TDS, EC, and temperature with a titanium alloy probe. Meanwhile, the included 50 test strips cover free chlorine, bromine, total chlorine, cyanuric acid, total alkalinity, and total hardness. Together, you get 11 parameters tested from a single kit.

This combo approach makes a lot of practical sense. You use the digital meter for the parameters you check most often (salt, pH) and the strips for the ones that need less frequent monitoring (CYA, hardness, alkalinity). The backlit LCD display is bright and easy to read, and the titanium probe delivers stable readings.

With 96 reviews and a 3.9-star rating, the feedback is mixed but leans positive. About 60% of reviewers give it 5 stars, praising the accuracy and versatility. The main complaints center on the battery compartment design, which uses stacked button-cell batteries that are awkward to install.

It is worth noting that the meter portion does not test chlorine. If you want chlorine levels, you need to use the included strips. This is not a deal-breaker since the strips are included, but it is something to understand before buying.

Who Should Buy This

Pool owners who want complete water chemistry coverage from a single purchase will appreciate the AKSBTEC kit. It is great value for getting both a digital meter and 50 test strips in one package. New pool owners who are building their testing toolkit from scratch will find this kit covers everything they need to get started.

Who Should Look Elsewhere

If you want a single device that tests everything digitally without relying on strips, the WaterGuru or Yewhick are better options. The button-cell battery design is annoying for users who prefer standard batteries. Those who only need salt and pH testing can save money with a simpler 5-in-1 meter.

12. GIDIGI 7-in-1 Digital Chlorine Tester – Best Backlit Display Pool Meter

The GIDIGI 7-in-1 stands out for two reasons: it is one of the few handheld digital testers that claims to measure free chlorine (FAC), and it has the best display I have seen on any tester in this category. The backlit color screen is a genuine upgrade from the basic LCD displays on most competitors.

In testing, the pH, TDS, EC, and salinity readings were accurate and consistent after calibration. The auto temperature compensation (ATC) feature means you get reliable results regardless of water temperature, which matters when you are testing in early spring or late fall when pool water can be significantly cooler.

The free chlorine measurement is the headline feature, but it comes with a caveat. Some users report that the FAC readings are not consistently accurate. I found the chlorine numbers to be in the right ballpark for routine monitoring but would not rely on them alone for precise chemical dosing. Cross-checking with a drop-based test is still recommended for critical adjustments.

The replaceable probe tip is a smart design choice that could extend the life of this meter significantly. Most digital testers become disposable once the probe degrades, but the GIDIGI lets you swap it out. With an 84% five-star rating and 4.6 overall score from 20 reviewers, the early feedback is strong.

Who Should Buy This

Pool owners who want a single handheld device that covers the most parameters, including a free chlorine estimate, will find the GIDIGI compelling. The color screen makes it the best choice for anyone who tests in low-light conditions. The replaceable probe also makes it appealing for long-term value.

Who Should Look Elsewhere

If you need guaranteed accurate chlorine readings for commercial or regulatory compliance, a dedicated FAS-DPD drop test kit is still the gold standard. Users who only need salt and pH can save money with simpler devices. The 12.3-ounce weight makes it slightly heavier than other handhelds, though it is still portable.

How to Choose the Right Digital Pool Chemistry Test Kit

Picking the right digital pool tester depends on what type of pool you have, how often you test, and what parameters matter most to you. Here is what I consider the most important factors after testing these 12 kits.

Key Parameters Your Tester Should Measure

At minimum, any digital pool water tester should cover pH and your primary sanitizer. For saltwater pools, that means salinity. For traditional chlorine pools, that means free chlorine or ORP. Beyond those basics, total alkalinity, calcium hardness, and CYA (cyanuric acid) are important for complete water balance.

The testers in our lineup range from basic 5-in-1 meters that cover salt, pH, TDS, EC, and temperature to advanced monitors like the WaterGuru Sense S2 that measures free chlorine, CYA, alkalinity, and hardness. Think about what you actually test for on a regular basis and choose accordingly.

Digital vs Drop-Based vs Test Strips

Drop-based test kits like the Taylor K-2006 are still considered the gold standard for accuracy by pool professionals. They use titration methods (like FAS-DPD) that provide precise chlorine measurements. However, they require more time, skill, and color-matching ability.

Digital testers trade a small amount of precision for speed and convenience. A probe-based meter like the Hofun gives you a salinity reading in 5 seconds, while a drop test might take 5 minutes. For daily and weekly checks, digital is more than accurate enough. For monthly comprehensive testing, a drop-based kit is a good complement.

Test strips are the cheapest option but the least accurate. App-enabled strips like the Droplytix improve the experience by using your phone camera to read colors, but they still cannot match the consistency of a good digital probe.

Calibration Matters More Than You Think

Every digital tester in this guide requires periodic calibration to maintain accuracy. Some, like the ORAPXI and T TESTRUST, include calibration solutions. Others require you to buy them separately. I recommend calibrating your meter at least once a month, or whenever you notice readings that seem off.

The calibration process is usually simple: dip the probe in a solution with a known pH or salinity value, press a button, and the meter adjusts itself. Skipping calibration is the single most common reason digital testers give inaccurate readings.

App Connectivity and Smart Features

Several testers in our lineup offer WiFi or Bluetooth app connectivity, including the Yewhick, AIPER, and WaterGuru. These smart features let you track readings over time, spot trends, and sometimes even get chemical adjustment recommendations. For data-driven pool owners, the trend tracking alone can be worth the extra cost.

However, app quality varies significantly. The AIPER and WaterGuru both have documented connectivity issues, while the Yewhick’s Tuya App connection has been more stable in my testing. Read recent reviews about app performance before committing to a smart monitor.

Waterproof and Durability Ratings

This is an area where many digital pool testers fall short. Most handheld meters are water-resistant but not fully waterproof. If you drop the GIDIGI or Terronix fully into the pool, it may not survive. Only the floating monitors like the Yewhick and AIPER are designed for continuous submersion.

I always rinse the probe with fresh water after each use and store the meter in a dry place. This simple habit extends the life of any digital tester significantly. The titanium alloy probes used by Hofun, YUZIIB, and AKSBTEC are more corrosion-resistant than standard metal probes.

Long-Term Cost of Ownership

The purchase price is only part of the equation. The WaterGuru Sense S2 has ongoing cassette replacement costs that add up over time. The Droplytix and AquaDoc Eagle Ray consume test strips that need regular restocking. Probe-based meters like the Hofun and YUZIIB have minimal ongoing costs beyond occasional calibration solutions and batteries.

Factor in battery type too. Standard AAA batteries are cheaper and easier to replace than button-cell batteries used by some meters. The Yewhick’s solar charging is the most cost-effective power solution in our lineup.

Final Thoughts on the Best Digital Pool Chemistry Test Kits

Finding the right digital pool chemistry test kit comes down to what you need most. For most saltwater pool owners, the Hofun 5-in-1 provides the best balance of accuracy, ease of use, and proven reliability with over 1,800 reviews backing it up. Budget-conscious buyers will find the ORAPXI 5-in-1 delivers solid performance at a lower price point.

If you want the most comprehensive monitoring with app connectivity, the Yewhick 7-in-1 Smart Pool Monitor is an exciting option with 7-parameter tracking and WiFi control. For hot tub owners, the AquaDoc Eagle Ray covers bromine and spa-specific parameters that other testers skip.

The most important thing is that you test your water regularly. Any of these 12 digital pool water testers will give you better, more consistent results than guessing at color charts. Pick the one that matches your pool type, budget, and testing habits, and start swimming in properly balanced water this season.
