    Water Test Kits

    1. 1 decade ago
      Plain & Simple
      I have had a pool for about 15 years now. Chlorine level and PH level have been all I need to keep the water crystal clear and PH balanced. Other family members have bought me more sophisticated testing kits but I have ended up just using the basics. As far as I'm concerned, "if it's not broke, don't fix it".

      Works Great!
      Purchased this for the start of the pool season. I love the seven water areas it tests. It really is a great help in keeping our pool water balanced and clean.

      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.

      So easy to use, I actually TEST my pool water!
      This is the way pool testing should be done! With my old liquid testers, I often only bothered to check the chlorine (and maybe the Ph), and then just let the rest go, rather than laboriously testing each parameter. But with these things, you'll find yourself WANTING to test the pool water, because it's kind of fun. OK, it IS fun: You just dip it, wait 15 seconds, and then compare the colors to the chart, and you then have SEVEN pool chemistry values in 30 seconds. (BTW: Don't bother with the 4 ... read more or 5 parm test strips. Just jump right in and get these 7 part strips, because you'll end up with these anyway, if like I did you start with the 4-bangers.) If you have a bit of chemistry background, and have used Ph test strips to test acid/alkali, these will seem like an obvious extension of that. But as with Ph strips, you need good neutral lighting (presumably sunlight is ideal), because it's a color matching system. The only "catch" is that some pool guys (like mine!), claim they are not accurate. And, for cyanuric acid ("stabilizer"), it's a known problem that the basic pool chemistry needs to be "almost right", or the cyanuric test will be off. But that may well be a limitation of liquid test systems as well. I don't know. I'm in the process of testing these against a liquid reagent system to compare the two. But so far, when I checked Ph via a Ph meter, the test strips were right on the mark. I'll try to remember to update this review once I get around to doing the cross-comparison. Parting shots: I'm betting the expiration date is way sooner than it needs to be (if you store them in a dry and cool place.) So maybe get a new batch and compare them to your old 'expired' lot to see when they REALLY "expire". That's what I plan to do.

      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.

      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?

      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

      Better then the dipsticks
      I used to use the dipsticks, they dont show you if your levels are low or high.. This test kit shows you if your : "Free" chlorine Total chlorine pH Alkalinity Is low or high so you can adjust. This is most important tools you can use. It's either Scrub or SWIM ! I prefer to swim so this is one of my tools.

      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.

    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
