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.

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.

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.

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 .

shows that test strips was delivered and was not

Junk! Never shoes a chlorine level and kept saying ph was low when it was actually very high.

The dye for chlorine and ph levels are washed away upon contact with water leaving the levels unreadable.
