    Water Test Kits

    1. 1 decade ago
      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.

      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.

      Unbelievably Accurate
      These Aqua Check Test Strips are awesome. They are easy to use, and very accurate. No messy drops and no counting drops. They are priced right and there are plenty enough strips to last for the entire summer in one package. I definitely recommend these to all of my friends. This is a must buy.

      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.

      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.

      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.

      AquaChek TruTest Test Strips
      I have used these for years and my readings have always been spot on with what The Pool places get with their test kits, for the items checked. It takes a few tries to do it properly, reading the instructions is a good place to start! Not trying to snipe at anyone, the instructions just elaborate on how to get a good reading...

      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

      Good water test kit
      The 4 way test kit is essential for all pool owners if you want to avoid water problems and expensive treatments to correct them. This kit is easy to use.

      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.

      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.

      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.

      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.

      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.

    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
