      Essential to a healthy pool
      I have used the Aqua Test Strips and Digital Meter for three years now. A base line for comparison: I use an automatic chlorine feeder with 3 inch tablets and the Natural Chemistry products for water maintenance. I have compared the accuracy with other traditional testing kits and find the results to be within 10% of each other. I haven't had an algae or any other water problem for three years.

      Helpful Product
      The range of test strips colors is so wide your guessing at the readings. The AquaChek TruTest meter helps me get a better results without guessing.

      iT DOES NOT FLOAT.
      I love it. A floating thermometer is not accurate because of the sun shining on it. I tether my thermometer on a line and it tells me the water temperature below the surface. I am able to read it despite my low vision.

      Big box with almost nothing in it
      I have no idea why this is so expensive but I opened this big thick plastic box to find four small chemical tubes in it. Should have been $19.95

      Easiest Product To Use
      I use the Aquacheck test strips at least once a week (or more if it's rained) for a quick and easy way to check my pool water. When the test strip indicates that I need to adjust pool chemicals, I use the Taylor DPD Test Kit since it gives more accurate readings than the strips. It's easy to use and the directions are right on the box. Plus it gives me peace of mind knowing that my pool's chemicals are exactly at the levels they need to be. And thanks to In The Swim, all my pool products are ... read more brought right to my door. Thanks In The Swim!!

      Love this kit
      I normally use test strips, but due to some problems with my alkaline and pH levels, I had to get real accurate - since then I've completely switched over to this kit, and hardly use the strips anymore. I'm here today to find the other test liquids so I can also use this kit to test for calcium and stabilizer.

      excellent product
      This is the best test kit on the market for a home pool owner. I have used many different kits in the past 15 years of owning a pool, and this is by far the best. Well worth the extra money.

      Excellent Product
      The Taylor Series of Pool/Spa Test products are by far the easiest to use on the market. I purchased this kit for both my pool and spa. I get accurrate results each and every time unlike the comparatively expensive test strips that are available on the market. This product is a must for anyone with a pool or spa!

      Worth the money.
      Bought this kit because I was tired of driving across town to the pool store and getting a different answer and $80 dollars worth of product every few days trying to get my pool chemistry right. It works like a charm. its easy to read and the the results are consistent. Took a couple samples to the store after I ran my own numbers to see if they were comparable and they were. Was able to balance my water and clear it up within days. Best 80 bucks I have spent on my pool this yr. The only reason ... read more I didn't give it 5 stars is because measuring the CYA level requires alot of product and I don't feel like it would last the season. Luckily CYA is one product that doesn't disappear in the pool water after you add it so the levels stay pretty consistent. If your one the fence and struggling to keep your pool water clean and clear. I highly recommend this kit. It makes knowing what your pool needs a breeze. Now instead of spending $80 every 3 days at the pool store trying to get my water clear. I can throw a couple gallons of shock in it about 1 a week and walk away. The water is clear and balanced and I am confident that it is not damaging my liner and is safe to swim in.

      Best Test Kit
      After purchasing my third different test kit I finally found the best one. It has all of the tests that I need in one kit. It takes all of the guess work out of the equation. No more trying to match a color or line up the camera in my phone to a card that does take the correct picture.

      water testing
      Purchasing this monitor for testing pool water chemistry was one of the best investments I made. The procedure is easy and the results have been, no more expensive chemical purchases. I know what I need and do not waste time and money to keep my water sparkling and clear. With less maintenance, we'ver enjoyed the pool more than ever! Isn't that what summer is all about?!

      Awesome Reader!
      I love the AquaChek! I have owned a pool for 16 years and have used every pool water tester in the book. I am done with the dropps and the mess. I like how easy the AquaChek is to use, just turn it on, dip a strip and place it on the reader. You get a reading in seconds. I also like the design of the device, it is built very solid and easy to hold. Maintaining a pool can be a pain but this product makes it a bit easier.

      Easiest test kit to use
      I use these type of test strips and meters all the time with diabetes, so I have some experience. Many other reviewers had problems with accuracy. The best instructions I got were from another reviewer: Dunk the strip in the water and immediately put in the reader (face down). With that, it produces fast, consistent results. This isn't really mentioned in the instructions. I have tried the other types of testing kits, and can never really tell if the color I see is out of range or OK. Having the ... read more meter is a tremendous benefit.

    Pool Water Testing FAQ

    Testing your pool water regularly is the best thing you can do to ensure clean and healthy water that won't make your swimmers sick. Water balance is when your pool has the correct levels of Chlorine, pH, Alkalinity, Calcium Hardness and Stabilizer. In addition to sanitary water that looks beautiful, balanced pool water protects your pool surfaces from stain and scale formation. 


    Why & When Test Pool Water? Testing pool water several times per week, is the only way to achieve 'water balance', so important for healthy, sanitary water because it affects the potency of chlorine, and creates poor living conditions for algae and bacteria. Balanced pool water also protects your pool surfaces and equipment from corrosion, etching, staining and fading. Good for all the soft and shiny surfaces in your pool; including the eyes, skin and hair of your swimmers. 

    Pool Test Kits or Test Strips? Pool test kits, those with liquid or tablet reagents are almost always more accurate or trustworthy than test strips, which may miss the mark by 10-20%, and can be more difficult to discern small changes in color. Pool test strips are fast and convenient however, and some pool owners use test strips several times per week, but also have a full test kit to run more complete pool water tests every week or two, or to verify and re-check test results from test strips. In addition to greater accuracy, test kits also have additional tests and charts to help in calculating the correct chemical amounts, when adjustments are needed.

    Best Test Kit for Pool Owners? The best pool test kit will be one that you will use - regularly. For a complete pool water Test Kit, the Taylor K-2005 is the standard in the pool industry. If you really love pool chemistry, or happen to be color blind, look at the LaMotte ColorQ test kits with digital colorimeter. For Test Strips, we carry the entire line of AquaChek strips and also strips by LaMotte and Frog. For complete pool testing, the AquaChek Select 7-way and the Insta Test 6-in-1 test strips will run the full battery of pool water tests. See also our Commercial Pool Tests Kits & Meters page for more water testers. 

    Ideal Pool Chemical Levels:

       - pH: 7.2 - 7.6
       - Free Chlorine: 1.0 - 3.0 ppm
       - Combined Chlorine: 0.3 ppm or less
       - Total Alkalinity: 80-120 ppm
       - Calcium Hardness: 200 ppm or more
       - Cyanuric Acid (Stabilizer): 30 - 50 ppm

    Pool Chemical Level Adjustments: Test strips will tell you what the current chemical levels are - but not how much chemical to add to raise or lower levels. A good pool test kit will also have acid demand/base demand tests, and chemical dosage charts, to help you better determine how much of what chemical, is needed to balance pool test levels. 

    Also important is to adjust each pool chemical individually. Allow a few hours for a chemical to take effect before adding other chemicals, or before testing and adjusting the same chemistry level again. For safety reasons, be sure to open only one chemical at a time, and never use the same scoop for different pool chemicals. 

    Pool Testing Pitfalls to Avoid: 

       - Store your test kit and test strips indoors, or in a cool and dry location. 
       - Completely rinse test vials before and after use
       - Do not interchange test reagent bottle caps
       - Hold test reagent bottle vertical when dispensing drops
       - Do not test surface water, but draw sample water elbow-deep 
       - Test a new sample, before making large chemical adjustments
