When you need serious filtration power without taking up space inside your tank, an external fish tank filter is the smart choice. Our External Filters collection features a range of canister-style and hang-on-back filters designed to sit outside your aquarium and deliver powerful mechanical, biological and chemical filtration — keeping your water crystal clear while giving your fish the maximum swimming room.
External filters are ideal for medium to large aquariums where internal filters simply cannot keep up with the bioload. They process much larger volumes of water per hour, hold significantly more filter media and run quietly in a cabinet or stand beneath your tank, completely out of sight. The result? Cleaner water, healthier fish and a much tidier-looking aquarium.
Our range includes compact models perfect for tanks from 60 litres, right through to high-capacity canisters rated for aquariums over 500 litres. Each filter comes with easy-to-use quick-disconnect fittings, self-priming pumps and layered media baskets that make setup and maintenance straightforward — even if you have never used an external filter before.
Not sure when to clean your filter? Most external filters only need a media rinse every four to eight weeks, making them one of the lowest-maintenance upgrades you can add to your aquarium. When it is time, simply disconnect the hoses, open the canister, rinse the media in old tank water and pop it back together.
All external filters ship Australia-wide from our Sydney warehouse with fast, tracked delivery. Browse the range below and upgrade your aquarium filtration today!
