Oxygen Profi Test Kit
The Salifert Oxygen Profi-Test is an extremely fast test that measures oxygen levels in just a few minutes, scaled from 2-14 mg/L; sufficient for 40 tests. Corals and marine fish require very high oxygen concentrations because of the low solubility of oxygen in salt water, so regular oxygen testing is important; usable in marine, freshwater, and garden pond water.
