Collection: Fish Filters & Media

Clear, stable water is the foundation of a healthy aquarium, and it comes down to filtration doing three jobs: trapping debris, growing beneficial bacteria and absorbing dissolved waste. This range covers both the filter units and the media that goes inside them.

• Internal, hang-on-back and air-driven sponge filters
• Ceramic noodles and substrate, activated carbon, zeolite, filter wool, foam pads, media bags and replacement cartridges

Size the filter to your tank's volume, rinse biological media in old tank water rather than tap to protect the bacteria, and swap cartridges on the schedule the pack suggests. Our aquarium filter types guide compares the main systems.
