Practical to install, safe in tightness and with a good mechanical and especially biological filtration capacity: Bluextreme is the external aquarium filter which answers to these requests! This external filter is ideal both for fresh and marine water, complete with filtering materials, pump and accessories. Bluextreme guarantees a direct flow of the water without preferential passages from the inlet to filter bottom and then to the different filtration stages.
Here is explained how it works:
in the first and second stage, there is a mechanical filtration with coarse sponge and then fine sponge. Afterwards, thanks to the active carbon sponge, absorptive filtration occurs; at last, there is a biological filtration with ceramic rings.
Bluextreme has an easy self-priming system, a safety lever for valves opening and closing and flow adjusting, an apposite lever to unblock and remove pipes fixing block. The tank made from shockproof material is resistant and inclusive of supporting feet; the hooks for filter closure are made from material filled with fiber glass. High tightness is guaranteed by gaskets in EPDM rubber and by ring nuts in non-toxic PVC with diameter of 15/21 mm. The pump is incorporated in the cover, has overheat protection and ceramic shaft included.
Availble as spare parts, you will find the active carbon sponges Bluclear and the mechanical sponges Blumec. If you like, besides, instead of active carbon sponges, it is possible to use the suitable granules of active carbon or zeolite.
