With all the features of the Pump Fed version this filter can also be buried in the ground and fed from a bottom drain. This is the most efficient way to filter the pond and allows the filter to be entirely hidden away.
There are basically 2 ways to achieve this. The best way is to use the Proficlear Premium XL Individual (undrilled chamber), which is a box of nearly identical size which connects to the Premium in series. The pumps and the UVs go inside the pump chamber. Water then leaves via an outlet pipe to return to the pond. Or you could use an Aquamax Eco Premium in the pump chamber feeding a hose out to the UV and then to the pond.
Alternatively you can fit an adaptor on the outlet to change this to a 50mm. This can then be attached to a dry mounted pump, like the Aquamax Dry, and the water then pumped through a UV and back to the pond via a hose.
Ideal for ponds of up to 530,000 litres (116, 584 gallons), or koi ponds of up to 100,000 litres (21,997 gallons). The gravity fed version can accept flow rates from 25,000 Litres/Hour up to 66,000 Litres/Hour.
Using technology from the highly successful and popular Proficlear Premium automated Drum Filter and Moving Bed Biological Filter, OASE Germany have packed all the same great features into one easy to maintain box. This unit is ideal for ponds of up to 530,000 litres (116, 584 gallons), or koi ponds of up to 100,000 litres (21,997 gallons). The pump fed version can accept flow rates from 25,000 Litres/Hour up to 50,000 Litres/Hour.
The self-cleaning drum technology can remove solids down to as little as 60 microns (60 thousandths of a millimetre) that's around half the thickness of a human hair. It then flushes the waste away using a small amount of pond water. The moving bed filter contains new media that have a significantly enlarged surface area. This aids in the growth of beneficial bacteria and increases the rate at which they can remove harmful ammonia, nitrite and other pollutants. A powerful air pump is needed to make the media move and create the "fluidised bed."
This pump fed module is designed to be set up above ground and have the outlet of the filter feeding back into the pond or on to a waterfall. A Bitron C UV or a Bitron Eco UV can be mounted on the inlet to effectively clump together the algae before it enters the drum.
The Proficlear Premium XL Drum Filter - EGC also features a digital control module through which you can perform a number of useful functions.
