The Filtration Process
    Water is pumped from pond Water under pressure is forced into the bio-reactors which trap dirt and debris. Beneficial bacteria convert ammonia, which is harmful to fish, into nitrate, which are consumed by aquatic plants. This is known as the Nitrogen Cycle. Filtered water is forced up the center tube. (Optional UV) Filtered water is returned to the pond 9ft. power cord on UV units.
The Backwash ProcessWater flow is reversed and forced down the center tubeThe water jets create a whirlpool effect in the bio-activator chamberDirt and debris loosened from the bio-activators Dirty water is discharged out the back-flush port into the garden
