Canister Filter Basics
Canister filters clean aquarium water by pushing it through several filter materials. They sit outside the tank and connect with tubes. These filters handle large tanks well and keep water clear.
Understanding how canister filters work helps you choose the right filter for your aquarium. They offer many benefits compared to other filter types like hob filters.
How Canister Filters Work
Water flows from the aquarium into the canister filter through an intake tube. Inside the canister, water passes through layers of filter media. These layers remove debris, chemicals, and harmful substances. Clean water then flows back into the tank through the output tube.
- Water enters through the intake tube
- Passes through mechanical filter media to trap debris
- Flows through chemical media to remove toxins
- Moves through biological media for beneficial bacteria growth
- Returns to the tank clean and clear
