UltraZap 15 litre (internal volume) Bio Filter Chamber for Ponds up to 7000 litres, 60 -100 litres/minute flow rate. Connectors are glue type fittings 50mm diameter. Install inline after particle pre-filter.
Bio filtration is a chamber containing living bacteria to capture and biologically degrade nitrogens in ponds. Bio filtration is required to break down ammonia into nitrite and nitrite into nitrate. Bio Media is used for biological filtration. The main advantage of bio balls over other biological media is that the surfaces are impossible to clog up (when used with a pre-filter). The reason is simple: the gabs of space within a bio ball is large and anything that can clog it up would already have been filtered by the pre-filter (such as filter wool, sponge etc). This is the reason why water filtration should always pass through mechanical filtration (pre-filter) before biological filtration.
Water pump and Bio Media is not included and sold separately. Bio Media can be found under FILTRATION MEDIA (or search Rebel Pets for Bio Media).
Use Hosetail/Reducer (50mm — 16mm) to adapt to differing PVC pipe sizes.
