OASE FiltoSmart 60

The FiltoSmart is a compact external canister filter for aquariums.

Using the FiltoSmart filter you can achieve crystal-clear water thanks to large surface area and multi-stage mechanical biological filtration.

Multi-staged mechanical, biological, and chemical filtration provides clear, healthy water and a high surface area for beneficial bacteria to colonize.

FiltoSmart 60 uses a coarse 20ppi filter foam and ceramic media, which provide a high surface area for beneficial bacteria to colonize.
Timing to replace the filter media varies upon aquarium size, number of fish and plants, and a decline in filter performance.
It is best to only replace the ceramic filter media when you do a complete tank restart as to not disturb the beneficial biological load.
