Aquarium Co-Op Multi-Test Strips
Aquarium Co-op test strips work awesome and are at a great price point. I've double checked parameters with my reagent kits and they are always right on line with what these strips indicate. More convenient and less time spent filling vials!
Awesome
I have a 55 gallon and a 75 gallon tank. Shot I thought everything was ok with both thanks until I bought these strips that exposed how wrong I was. The nitrates were out of control the GH, KH, PH were all way above what they should be. Now I have some work to do thanks aquarium co-op without these strips I never would’ve known.
Perfect to check water quality when starting a new tank or quick daily checks
They work great and exactly what I needed. Would recommend.
Works great! Very fast and easy to use helps me test more often which we all need!
Quick, easy, and accurate. I'm left with no excuses to test my water.
I love this product. Very accurate and easy to use
These strips are a quick and easy way to get a quick read on water quality in your aquarium. They can be cut in half for even greater value. The only issue is a false chlorine read under sunlight- bring that tub water inside to test!
