OXYGEN INJECTORS

Airstones or other bubble making devices work fine for aquariums and other low biomass density fish cultures, but when you are trying to grow as many fish as possible in a tank you had better have something a lot more efficient to get the air dissolved into the water. Seeing bubbles rise to the surface might make you feel good about things but when bubbles come up, that means the air did not get to a place where the fish can use it. The solution to this problem is through oxygen injection. It was learned hundreds of years ago that when oxygen is placed into water under pressure, the oxygen molecule is forced into
the water molecule, hence the term, “Injection” .

Most low pressure oxygen injectors found in the market place today (as well as older models from Global Aquatics) are large and bulky devices that are difficult to fit into most tank systems. Through many experiments and design changes, Global Aquatics has now developed an injector that is only inches wide. This allows for the unit to be set right on the end of almost all tanks.

This unit is designed to carry 40 gallons per minute and develop 15 psi of pressure. The most effective way to use this unit is to have the water returning from the biofilter pumped directly to the injector and then directly into the fish culture tanks. By doing so the water and excess, un-dissolved, oxygen leaving the discharge nozzle will have yet an additional opportunity to be dissolved into the tank water.
