Match the filter to your aquarium volume and give yourself a little headroom. Heavily stocked or planted tanks benefit from sizing up for extra turnover. All three models run in freshwater and saltwater and use quick-swap cartridges for easy upkeep.

FAQ

Where does it mount?
The Aqua Filtra hangs on the back rim with the filter body sitting inside the aquarium, so it takes up very little space behind the tank.

What filtration does it provide?
All three stages in one cartridge: mechanical (sponge), chemical (activated carbon), and biological media for beneficial bacteria.

Freshwater or saltwater?
Both. The Aqua Filtra works in freshwater and saltwater aquariums.

How do I replace the media?
Swap the all-in-one cartridge. The 10 and 20 share the Aqua Filtra 10-20 cartridge, and the 40 uses the Aqua Filtra 40 cartridge.
