All-New 2023 Pool and Spa Test Strips 7 in 1 Quick SuperAccurate Swimming 150 Pool Test Kit - Hot Tub Test Strips & Pool Water Testing Strips for pH Chlorine Bromine Hardness Alkalinity Cyanuric Acid

Very important

Although well sealed and its too early for expiry date and looks 100% new, the strips are a complete shock. All readings cannot be compared with the Color Chart in particular ALL READINGS!!. I am completely disappointed for the time and money lost. Yes I observed all instructions carefully.And because of wrong readings I added some SpaGuard PH Increaser and next day added some more SpaGuard Total Alkalinity Increaser!. All the results were same, showing only YELLOW COLOR which is not related to Color chart at all!My granddaughter can no longer use the pool for the time being!Today a family member who have similar INTEX 260x160 cm pool tested the pool water with the tester they use and the results were frightening!Now I have to drain some or most of my pool water to fix what the strips destroyedMay be returning these test strips in near futureI have to look for something else

This Pool & Spa pool tester is accurate, easy to use and super easy to intrepret the results! We simply remove a strip from the bottle, dip it in the pool for a full 5 seconds, and line the individual strip readings with the legend on the side of the bottle! Viola!We compared the result with a printout from a well-known, nationally known pool store comprehensive pool water analysis print-out after we drove a test bottle sample into the store: Guess what? The Pool & Spa test strip results lined-up perfectly with the national pool store printout!!This will save us a lot of back-and forth drive time from the pool store for automated testing from their computer and pool water test instrument!For reference, we are in the greater San Diego area where it is important to test our pool water 2-3 times per week in the summer season!This product: FIVE STARS ☆☆☆☆☆

Price was just right for how many tests you get in 1 without breaking the bank. Like many other reviews, the accuracy is similar to that of the liquid drops and pro analysis in the store.Hold in water for 2 seconds, compare results within 10-20 seconds after removing from water, and adjust your chemicals as necessary.Reading these in daylight is much easier than at night with a flashlight, but don't let it dry out too much before a read...it will show less than actually there. Keep stored in a cool, dry place....this is key to their longevity and accuracy. Even outdoor coverings such as sheds and cabinets dry them out to a point where they are inaccurate.Would happily buy again. I've worked on small to large pools and this time for an inflatable spa...works every time and is as accurate as can be. Your mileage may vary depending on your skills/practice with pool/spa chemistry but key is to adjust PH first and alkalinity next before you go tackling multiple issues...chlorine is key once those are level.

Test strips seem to be accurate, easy to use

Received them in good condition, and I’m very pleased with the product.

I have almost gone through one of these and have purchased a second so I don't run out. I've been very happy with the test strips and feel they are a good value. They get the job done and with a 150 count I find I test more often which has helped me keep my hot tub in shape.
