Hozelock Trinamic Pond Filter

The Hozelock Trinamic koi pond filter gives outstanding performance for excellent water clarity, outstanding water purity for optimum fish health yet has been developed to be quick and easy to maintain. This makes the Trinamic one of the best koi filters on the market.

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

Stage 1 - Moving-bed biological filtration for healthy fish.

The water enters the filter at high velocity and spins unique Kalnes K3 biomedia chaotically around the bio-module. A venturi introduces oxygen to the water. The beneficial bacteria growing on the inside and outside of the K3 biomedia thrive in an oxygen-rich enviroment and breakdown harmful soluble pollutants at a very efficient rate.

Should sludge collect in the K3 bio-module it can easily be flushed to waste via the sludge drain. The Trinamic filters can support the same amount of fish as much larger filters but are much easier to hide near the pond.

Stage 2 - Fine foams for crystal clear water.

Water passes evenly 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 - Denitrifying bacteria provide an important second biological process.

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