The Oase BioPress 4000 Pond Filter offer easy and convenient cleaning of the internal filters via the cleaning mechanism. Quick release lid clips also provide easy filter opening and closing for maintenance purposes when required. These filters contain different grades of filtration foam for optimal waste removal and allow high levels of friendly bacteria to colonise the filter. The Oase BioPress 4000 include an integral Ultra Violet Light with an indicator window which makes it simple to see at night if the UV bulb is working. The Oase BioPress filters can be hidden at the side of a pond or buried in the ground up to the level of hose inlets and the pressurised design of the filter allows the water to be pumped to a higher exit point to feed waterfalls and streams and unlike other filter units the outflow water pipe can rise up to 2m from the filter location (provided the pump is powerful enough). Supplied with a 2 year product guarantee and has Oases' a clear water guarantee.

What is Effective Volume ?
The effective volume is the quantity of water in your pond, plus an allowance for shallow and or ponds exposed to high levels of sunlight. Both of these situations will result in a higher than normal algae growth, and fish pollution. We advise that to ensure your that your equipment is correctly sized, the effective volume be considered the minimum size for the equipment you select. However do remember to check the details of the product you are interested in, to ensure that there are no other allowances or consideration specific to that product are required.
