HTH 6-way Pool Test Strips, 30 Multi-use Test Strips for Chlorine, Bromine, pH, Alkalinity, Hardness, CYA

These sticks are fantastic!!! They are accurate and use the app it makes pool maintenance so much easier. My family are enjoying having a summer with a pool in the back yard!

These strips are very convenient. We live in an apartment building and the chlorine smell was too much. So I bought these to check the levels, which were normal.

These never seem to turn any colors except for the chlorine one. Every time I text it to the number it says it cannot read the test. Not a good test strip for anything other than chlorine.

About halfway through the bottle of strips I noticed these were not working correctly. I started getting readings that I needed 40 pounds of pH Down and when I took to our pool store they actually said I needed PH increaser. I just bought these strips in june and keep them in the house and do not leave the bottle open but they are no longer accurate.

You substituted this product for the one I ordered without my permission. Then the pick up is impossible without using your stupid app. Why post a phone number at the pickup station if no one will answer it? You like frustrating your customers?

I dont think they work. The packaging and instructions are good. I put them in the water then counted out the time. I had to wait 4xs the time for a read. The date is good, not old. Compared to my other test strips these are not worth it.

Chlorine reading is not accurate. It was white every time I tested over a 3 week period. I changed brands and the chlorine levels were fine all along.

Not real sure how acurate these test strips are. They seem to be easy enough to use though. The HTH Pool app is a joke because it hasnt been updated and you can not even download the app on newer devices. My device is actually several years old and I still cant get the app. I have an old Samsung Galaxy S10 Plus and it tells me the app is made for an older device and is unavailable for downloading. I will be returning my test strips because of this. You can also text a picture to a number it says but if your phone camera isn't great then how accurate could a picture be?

I did not pay attention to the package when I ordered, these HTH 6 way test strips are horrible. The color contrast after dipping the strip is indistinguishable. The chlorine colors especially are a terrible shade of pinkish nothing. It is hard to tell what your chemical levels are. I normally use the SMART TEST 6 way test strips. They color up properly after dipping and make it so easy. I wasted my money on these strips, wish I could return them.

I had these and clorox test strips. These read completely different than the others. I texted them the picture of the test strip and they suggested I add 38 pounds of pH additive to my 11,000 gallon pool!!! I went to my local pool company with a water sample to make sure and the HTH strips were way off. I chucked them and am sticking with the clorox strips.
