Aquarium Canister Filters
Aquarium Canister Filters in India
Canister filters are the workhorse of medium, large, planted and cichlid aquariums. Sitting hidden in your cabinet, these external filters pump water through large trays of mechanical, biological and chemical media for crystal-clear water and rock-solid biological filtration, with less noise and far longer gaps between cleans than smaller filters. At Fish Bazaar we stock canister filters from Fluval (107, 207, 307, 407 and the FX series), Aquael (Ultra, Ultramax and Hypermax) and OASE, shipped across India.
Choosing a canister filter online in India comes down to your tank volume and stocking. As a rule of thumb, aim for a filter that turns your tank over 4–6 times per hour for community tanks, and higher for messy cichlids, goldfish or turtles.

Frequently asked questions
What is a canister filter? An external filter that sits below the tank and pumps water through sealed trays of media, giving powerful three-stage (mechanical, biological, chemical) filtration ideal for planted and heavily stocked tanks.
Which canister filter size do I need? Match the filter's rated tank volume to yours and leave headroom, for planted or cichlid tanks, pick a model rated for a larger tank than you actually have.
Is a canister filter better than a HOB? For tanks above ~150L, or planted and cichlid setups, canisters hold more media and run quieter. Smaller tanks are often perfectly served by a good hang-on-back filter.
