A simple filtration option for gentle-flow freshwater setups, fry tanks, and quarantine systems. Air lifts water through the filter while the sponge traps debris and the biological media provides surface area for beneficial bacteria.
What you need
An air pump rated at least 2 W and airline tubing are required and sold separately. Choose an air pump with suitable output for the installation depth and protect against back-siphoning according to its instructions.
Included
- One large filter
- Filter stone
- User manual
Maintenance
Rinse the sponge gently in removed aquarium water during maintenance. A new filter needs time to develop biological filtration; continue testing ammonia and nitrite.
Pairs well with
A suitable air pump, airline and check valve, plus an ammonia monitor for a quarantine setup.
