4.2.3 Filters
Conventional filters are usually designed on two working-principles: A. Aquarium water is siphoned into filter unit where it is allowed to slowly pass through one or more filter media before being pumped up or air-lifted and returned to the aquarium tank. B. Aquarium water is allowed to pass through the substrate at the bottom in a continuous circulation which is maintained either by air-lifting or by powerhead. Most filters combine filtration with aeration (for optimizing dissolved oxygen concentration of aquarium water). Various measures are taken for aeration. Canister Filter |
