Salifert Oxygen O2 Test Kit
Oxygen is highly essential for all life forms. Especially corals and marine fish require oxygen concentrations at saturation level. This is because of the low solubility of oxygen in saline water which is approx. 5 - 7 ppm.
The oxygen test measures oxygen concentration in just a few minutes.
Approx. 50 tests per kit. Range: 2- 14 ppm.
