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

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 .

these test strips have a clear marking on the side of the container, but you can also download the HTH app to use for clear and concise readings with recommendations and explanations . I have used many test kits in the past and this is the most clear, concise and you understand exactly what you need to do.

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.

Missing an item—the most important one

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.

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.

Easy to use test strips combined with the app which provides concise and easy to read instructions makes this novice fool boy into an expert Pool boy

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.

We never received these pole strips. They were not in any of the bags and we looked around outside. Nothing there.
