- Tetra filter cartridge
Instructions
Hang the Tetra filter canister on the edge of the aquarium. Position the canister near the back of the tank to ensure it doesn't block the aquarium lid from closing properly. Push the suction cups on the back of the canister against the glass to prevent the canister from moving in the water.
Insert a Tetra filter cartridge into the slot on the top of the Tetra filter canister. Slide the filter cartridge behind the bacteria sponge in the canister. The bacteria sponge is a black permanent sponge filter and is never replaced, but needs to be washed with warm water every time you change the tetra filter cartridge.
Plug in the power cord of the Tetra filter canister into the nearest electrical outlet to begin water filtration in your aquarium.
