Product Details
Kaldness (k1) media can be retro fitted into this filter in bay 2 by transferring the brushes from bay 2 to bay 1.
The recommended amount of k1 for this filter would be 25ltrs if aerated and 50 litres if static.
Few manufacturers in the world have put as much effort into designing a flexible and good value range of multi-bay filters suitable for the koi pond as cloverleaf, and how refreshing to not only know that they are british but to acknowledge they offer first class technical support to customers.
Key features of this well constructed compact "cl" range are the options of the filters being pump or gravity feed (meaning below ground), whilst meanwhile being very simple to maintain.
The incorporation of vortex bays, and skilful use of mechanical and biological bays using quality mediums encompassing good water flows are further attributes that make the range a superb and sound investment.
For very large ponds all filters can be happily installed as pairs - linked to separate pumps or bottom drains. All systems are supplied complete with valves and waste kits, together with a heavy duty lid capable of withstanding the weight of most pondkeepers.
The beneficial features are numerous, starting from the principles of up and down flow through the tanks thereby keeping the water in contact with the mediums for as long as possible.
Apart from the advantageous separation and settlement of solids in the vortex bay, the generation of an "upflow" and the incorporation of settlement areas (with drain down valves) ensures that the filtration mediums stay cleaner for longer – thus promoting larger colonies of beneficial bacteria, and by default thereby establishing a healthier pond environment.
The clever design layout of the vertical transfer ports also provides the highly useful bonus of being able to incorporate air stones (where desired) without the need for the pond to appear similar to a witch’s cauldron.
