Biosmart filters
Integrated UVC
Biokick CWS starter bacteria

Biosmart filters include Oase distinctive filter foams, with maximum surface area for beneficial bacteria, which transform toxic ammonia and nitrate into harmless nitrogen. Foams are easily squeezed clean, in situ, by the innovative compression mechanism


Integrated UVC Technology The integrated ultraviolet clarifier (UVC) ensures safe elimination of algae and pathogens on the Biosmart 7000 & 14000 filter models.


The optional use of OASE BioKick filter starter will dramatically increase the amount of beneficial bacteria within the BioSmart Filter and will colonise the filter foams to help break down waste matter organically.
