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.

The strips are a lot easier to use than the bottle ones

I like the IDEA of this, but it fell short. also when I was looking for test strips i want 100 at a time. not 35. I feel like I ordered a big pack and got the small size instead. reached out to customer service and they fell short as well. buy the cheaper ones from another brand that have much more strips. They work better. I personally liked the kind of strips that came with the "In The Swim" basic kit. these test strips by HTH are inaccurate, and the app is useless.. Buy another brand and follow the chart that comes with the bottle instead of dealing with this waste of money. I wrote this in a hurry so there may be grammatical errors. I wasn't even going to write a review, let alone a long one. but if you're considering, please consider the amount of negative reviews and don't do what I did which was ignore them.

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.

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 .

There is not one test strip in the bottle! It's completely empty.
