Qpets® 50pcs Water Testing PH Testing Strips, 14 in 1 Water Testing Kit Aquarium Test Strips Professional Freshwater Water Testing Kit for PH GH&KH Nitrite Nitrate Chlorine Carbonate

The strip is very easy and fun to use. It perfomance is also good . It's quality and accuracy is pretty good for a strip like these and the material made up is also very good quality. Also need to tell it's kinda worth the cost because you get 50 strips and it's very good for pools , testing house water and even for projects , it's perfomance was good and it has multiple functions .

Not sure if it is a packaging issue or the product itself, but once you open the bottle seal, the rest of the strips quickly went bad with all the indicators developing stains. if the tester strips are this sensitive, the bottle should have a tight enough cap to prevent moisture from going in. had to throw away the whole thing after using maybe 4 strips.

This works for project

It came in handy when I was panicking over nitrate levels so giving it 4 stars— however I was constantly doubting the results since the shades of nitrates are close by and tend to change between 30sec (recommended time of check) - 1min of checking time- so wasn’t 100% sure

It works pretty well, helps me maintain my water parameters. And it's cheap

Doesn’t give very accurate information of different parameters of the water, but will do. If there is a little change in nitrate n nitrite levels you can not make out from this test kit.

Only the first time after the seal was opened the strips worked. One week later it stopped working. Go for solutions, strips are pretty useless

It accurately reads the clear water parameters, but not when almond leaf tannins present ..
