    Water Test Kits

    1. 1 decade ago
      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

      Unbalanced
      I have been having a problem with my pool this year and after the hurricane l decided to stop fooling around. I didn't believe my old test kit was accurate so l bought this. I got different accurate reading this time and can treat the water properly for excellent results.

      Very easy to use
      We are new to pool ownership and testing our water was low on our to-do list untill to turned a brilliant shade of emerald green! Now we test regularly with this kit and it's much more accruate than the strips. I like the instruction card with everything you need on one page.

      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.

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

      Easy to use and very accurate
      I used this kit and compared the results with those received from my local pool company test. They were the same.

      very convenirnt
      For the pool owner who does not want to run to the pool store for every water check. All you need in one compact test kit. Very easy to understand directions.

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

      increaser-PH
      PH increaser- bought 1 mo, works great, only had to use 1 time so far

      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.

      Phosphate removal
      Gives a general level of phosphates. Realy need one giving PPB. I have a salt pool need to keep phosphates low, this is helpful but not exactly what I expected. Water companies put phosphates in water to protect piping, not conducive to salt pools, must be removed. There are HD phosphate removers out there Phosfree only keeps small quantities under control.

      I use this to test my pool water. We live in the country around farms, so we het phosphates constantly from them spraying.

      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.

      Great Products
      I always buy my pool supplies at In the Swim and usually have great service. Last time I ordered I accidentally ordered the wrong test strips and realized this when I printed off my receipt and immediately contacted them to have them send the right ones. I was told the order had already been processed and they couldn't stop it. It had been less than 5 minutes??!! I don't understand how their system works but seems there should be a way to change an order within a set period of time.

      good product
      I had previouslypurchased similar product from my local pool store but I like these strips better. They give you a better reading of all the various levels so you can better control water balance. Takes out more of the guess work.

      Great Item
      This thing works great Iam done with the strips I love it

      OK but an not completly satisfied
      I purchased this to get better reading on pH and free chlorine. I didn't need the salt, ORP and TDS but figured, no big deal. The instrument give me much more precise pH readings than test strips - happy about that, but the instrument sequentially then test for salt, TDS and ORP, which may take 2-3 minutes (all the while, I am waiting just to get to the chlorine). Once it gets to chlorine, it provides a qualitative answer (good) verse a numerical result (3.1). I wanted the numerical result. Would not buy again

    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
