Aquarium Filters

About

Aquarium filtration keeps your water clear, stable and safe by removing waste and growing the beneficial bacteria that break down ammonia and nitrite. The right filter depends on your tank size, livestock and how heavily it's stocked, so it's worth choosing the right type rather than the biggest or cheapest. Sponge filters are air-driven, gentle and inexpensive. With no intake slots and a soft flow, they're the standard choice for shrimp tanks, breeding setups and fry where stronger filters would trap or stress small livestock. They provide mechanical and biological filtration in one simple unit. Internal filters sit inside the tank and use a powered pump for stronger turnover. They suit small to medium community tanks and are easy to install and maintain without external plumbing. Hang-on-back (HOB) filters mount on the tank rim and draw water up through media before returning it. They offer strong, configurable filtration with easy media access, making them a popular all-rounder for community aquariums. Canister filters are sealed external units that push water through large volumes of media. They deliver the highest capacity and water polishing, ideal for larger, heavily stocked or planted tanks where you want powerful filtration kept out of sight. Filter media and bio chambers let you tune any setup, adding dedicated mechanical, biological or chemical stages for clearer, healthier water. Not sure what you need? As a rough guide: gentle, fry-safe tanks favour sponge filters; everyday community tanks are well served by internal or HOB filters; and large or demanding setups benefit from a canister. Note that air-driven sponge filters need an air pump and airline, usually sold separately. Browse the full range below.
