Integrated Heater

Provides precise and uniform temperature levels and reduces the amount of equipment seen inside the aquarium by housing the heater in the unit.


The BioMaster canister filter includes a pre-filter module that can be removed seperately from the rest of the filter. This reduces maintenance, increase filter efficiency, and extends the life of the main filter foams. Customize the pre-filter with coarse 30 ppi, fine 45 ppi, ultra fine 60 ppi, and activated carbon 45 ppi filter foams.
