HTH Pool Care 6-Way Test Strips, The Container Holds 35 Strips that Test for Six Elements in All Pools and Spa Types, 35 Piece Count

These strips take all the Guest work out of pool care. I love the app. I can take a picture of the test strip and it tells me exactly what I need to add or if everything is all good. Of course, I can always use the back of the container as well. I would definitely recommend these.

I use these pool strips when I'm too lazy to break out the full chemical testing kit. Some folks have said that they are not very accurate, but I have done the normal testing kit with the drops and then tested with the strips and the results came out the same. I always keep them inside in a storage box because I don't want the heat or humidity to affect them. They have been working great so far.

product provides a clear scale and evaluation of pool.

it's a product i use daily

Great not the first time I used this

I've been testing my pool water for 20 years using mostly Aqua Check strips. This was the first time trying HTH and the colors of the dipped stick do not match the colors on the bottle or using the online app. The color tones are wrong, not just washed out.

tested multiple strips one after another everyone of them shows a different reading and they was not even close to each others readings

If the strip isn't held perfectly level after dipping, the indicator colors bleed all off the little pads. Makes it very difficult to analyze the readings.

Maybe this is old stock I got delivered, but these are wildly inaccurate. I looked at the results after the first test and thought "what the heck, that can't be right" tested with 2 different test kits just to double-check and this one was the only one with the way-off weird results .

I had questions after my first two tests, as some of the readings weren't making sense (CYA and Hardness) with what I was seeing in other tests of the water. I took a sample to the pool store and it showed much different readings. I have now checked the results over the past month and all showed much different (and more accurate) results. I will not rely on these strips again.
