Tetra Test Oxygen

Description

Oxygen is vital for all organisms living in your aquariums or pond. Fish, plants and micro-orgasnisms all require oxygen for respiration. Having A concentration of oxygen that is too low results in oxygen deficiency and will lead the fish to be increasingly susceptible to disease. The bacteria that break down harmful substances also require a sufficient supply of oxygen. The oxygen concentration in the water of your aquarium or pond is dependent on a number of factors, particularly temperature.
