Great, and inexpensive!

These have hardness and alkalinity tests on them, which seem to be accurate. They are SO much easier than the "wet" test solutions, and cover everything I normally test for. No cleanup or counting drops.
If you buy the 200 pack they cost less than 10 cents each, so you can test very frequently.
Seriously, these are a great product at a great price!

Really do the job

This is my second order of the CoOp's test strips. I'm very pleased with the convenience and quick results. I still had quite a few left from my last order of two years ago, but it was time to get a new supply I was getting colors to rival the NBC peacock and I know that wasn't right! I ordered the smaller pack and I will see long that lasts.

These test strips confirmed what I suspected.

I was having trouble with my aquarium water PH but was not sure why. The Aquarium Multi Test strips confirmed we have hard water. Thanks to the GH & KH tests. Hopefully, I can fine the cure soon!
