  • 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 Process

    • Water flow is reversed and forced down the center tube
    • The water jets create a whirlpool effect in the bio-activator chamber
    • Dirt and debris loosened from the bio-activators 
    • Dirty water is discharged out the back-flush port into the garden
