How the manufacturer says to use the ammonia remover pads
The manufacturer positions the pads as chemical and mechanical filter media for Fluval FX4 and FX6 canister filters. Directions call for replacing each pad once a month, or sooner if testing with a Fluval test kit (sold separately) shows it is required. The pads are also listed for use after medicating fish.
What the two filter functions do in the canister
Each pad combines chemical and mechanical filtration, so it is intended to reduce and control toxic ammonia spikes while catching floating debris, excess food and waste. The manufacturer recommends the pads for new aquariums and for tanks with a heavy fish load. The same pad fits both freshwater and saltwater setups.
Which aquariums and filters take this media
Check that your filter is a Fluval FX4 or FX6 High Performance Canister Filter before ordering, since the pads are shaped for those models. The pads suit freshwater and saltwater aquariums, and the manufacturer lists them for new tanks, heavily stocked tanks and use after medicating fish. Each pad measures 5.5 x 16.5 x 20.5 cm, and the pack weighs 100 g (3.5 oz).

Which Fluval filters do these pads fit?
