Nitrite NO2 Test Kits

Nitrite is produced by fish waste and uneaten fish food. Low levels of nitrite inhibit respiration and suppress the immune system; high levels can cause suffocation and fish death.

This kit contains: Liquid dropper bottle with child-resistant saftey cap, easy-to-read instructions with information on how to test and how to correct unsafe water conditions, colour chart and glass test tube with a snap-tight cap.
