Hozelock Trinamic Gravity Pond Filter

The Hozelock Trinamic Pond Filter deliveres excellent water purity for healthier and more active fish. As the name Trinamic suggests, this is a 'three stage process' incorporating a 'dynamic' moving bed of Hozelock Kaldnes K3 biomedia.

Stage 1
The water enters the pond filter at high velocity and spins the unique Kaldnes K3 biomedia chaotically around the bio-module. A set of venturi introduce oxygen to the water.
The beneficial bacteria growing on the inside and outside of the K3 biomedia thrive in an oxygen-rich environment and breakdown harmful soluble pollutants at a very efficient rate. Should sludge collect in the K3 bio-module it can be easily flushed to waste via the sludge drain.
The Hozelock Trinamic filters can support the same amount of fish as much larger filters but are much easier to hide near the pond.

Stage 2
Water passes evely through a perforated plate and into a series of fine foams, which remove solid matter.
An indicator alerts the user when the foams need to be cleaned.
Once cleaned away, any remaining sludge from the foams can be flushed away via a sludge drain at the end of the filter.

Stage 3
Below the foam water passes through denitrifying bacteria, which grow on Cypripak biomedia in a dark still environment.
Clean healthy water is then returned to the pond.
