    Water Test Kits

      Makes test much easier, no colors to try and match
      I have only used this about 5 times but very easy, directions make it easy once you get the hang of it.

      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.

      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!!

      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.

      good testkit
      This kit is very easy to use. It has reference cards to help calculate your amounts needed based on your pool size. So far, our pool is crystal clear using this as our only test kit.

      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.

      Great test kit
      Just wish there were more of the regents that you use more. Some regents may last years and some a month depending on how high your chlorine is

      Accurate Readings
      Test strips seem to be giving an accurate reading. I do not have anything to compare against but the pool water looks awesome It was a little cloudy; the test strip was showing me low on chlorine. I added the chlorine the test strip read good for pool and the water is sparkling now.

      These are the first ACURATE test stips I've found!
      I was skeptical when I purchased the 'AquaChek Select 7 Way Test Strips' but, after using them, I'm so glad I did! I've used other test strips before and their accuracy wasn't that great. They would be okay for say PH, but not accurate for Chlorine, etc. In fact, it got to the point where I would drive to the pool store to have my water tested because I didn't trust the results, and as it turned out, it was a good thing I did. But these strips are accurate every test, every time! And results are ... read more fast, 15 seconds for accurate results. PS - did I mention they are accurate?

      7 Way Test Strips
      At first glance, you would think that these strips would not dial you in that well on your chemistry. After using them for three years now, I've found that they really do. I rarely go to the pool store for a computer water check anymore. These strips are so quick and easy that I can check my chemistry as often as I like. The vaules to be in shown by the strips have proven to be very accurate. When I keep my pool within the guidelines, I have no problems with the pool.

      Another great high tech gadget
      Wow is this thing sweet. Easy to use, just dip in water, and place on meter and press the button and 10 seconds later you have every thing you need to know. No more drops, no test tube things, no more making sure you have the right amount of water in the test tube, and no more color matching, just a small test strip, and meter. Plus another high tech. gadget (witch I love to have).

      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.

      Works for Me!
      I bought this tester to use for a quick daily test. If we have doubts about the results we break out the drop tester and so far the tests have been very close. I am very pleased with the ease and speed of the results. Not having to hassle with the drops is a big plus and getting quick results is just an additional bonus. I would have no problem recommending this tester to anyone.

    In The Swim Knowledge Pool: Pool Test Kits

    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
