Very quick and easy; great value

The title says it all, but that didn't stop me from cutting them in half to save more (haha). These are so convenient compared to a liquid test kit, and I don't think you will find any close price-wise. I'm quite pleased with these. I wish it was scientifically possible to have the ammonia test on the same strip too, but I understand that pesky chemistry is making things tricky. Do be aware that after a few minutes the colors will start going funny, so you have to look at the results right at 1 minute.

The only test strips I will buy

First time buying these test strips. They are easy to read with clear instructions on when you should change your water.

Aquarium multi test strips

The strips are easy and quick to use. Seem very accurate. I won’t bother to test my aquarium very often if it takes too long. These strips are so easy I test on a regular basis.
