These test strips are very easy to use. I dipped each one into my tank water and followed the color chart. I noticed a nitrite spike that I hadn’t seen before. Thanks to this test, I was able to take action and adjust my filter. The results were clear and the instructions were straightforward.

Great value for the five parameters tested. I used them to check my pH and nitrate levels regularly. The strips don’t fade and the color changes are easy to read. I recommend them to any aquarium owner.
