      liquid pool test kit
      I bought this kit to replace an old one. The test procedure was slightly different, but the instructions were clear and easy to understand.

      Pool water test kit
      Easy to use and very accurate. I have always use test strips in the past and they did not perform well. With this test kit, I know exactly what chemicals to add to keep my pool perfectly in balance.

      fast delivery
      Bught reagent refill 1 month ago. All of the reagent bottles will not produce a consitant drop size. Many times they will not produce any drops when squeezing the bottle slightly. In order to get a acceptable drop, the bottles have to be sqeezed hard, creating a reagent stream. After doing this, the drop action is acceptable. Unfortunately, this creates a unecceptable waste of reagents. I am very disappionted !!!

      Great for Color Blind People
      I have been using this tester for two years and love the ease of use. Being color blind it was a pain to chase my wife around to get her to read results. Now I can do it all in one shot. I do agree results vary from dropper testers but if you just rely on this test you will be okay.

      AquaChek Digital Test Kit
      I purchased this meter 7 years ago because I am color blind and had problems reading the manual test strips. Store that I purchased hot tub from was 20 miles away. I find this tester very sinple to use and very durable for I have dropped it several times. I use it to check the pool in the summer and Hot tub year round. The chemical levels are a little different for the pool vs. the tub but that is not a problem with this meter. I find it much easier to add the correct amount of chemicals once I ... read more collected enough data from this meter. I still take my pool water to the pool store for the first test each year but I maintain the correct levels throughout the summer using the meter.

      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.

      Easy testing
      I like this test kit because the instructions are in the lid and don't get lost or disintegrate if they get wet. With other kits, the instruction sheet was quickly rendered useless, so if you didn't remember how to use the drops, you were out of luck.

      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!!

      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

      Best pool water test kit I ever owned.
      Use it weekly, to maintain pool water, great way to use less chemicals.

      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.

      Easy & Efficient
      This test kit is easy to use and accurate. Much better then the color matching. The bottles last me about 1.5 months with daily testing. The only problem I have had with this kit is that the tester didn't work after the first summer the pool was open, about 3 months. I did keep it outside at our pool house so I don't know if cold affects it that much. The price is not so bad, but I don't want to have to buy a new one each summer.

      Consistent
      Consistent results - I can confidently add chemicals with this kit.

      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.

      7 Way Test Strips
      Good value! Color differences are not as stark as they could be so exact numbers are difficult.

    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
