Both figures are Fluval's rated output through the installed media, not a bare, unloaded pump figure, so they reflect what the filter actually does once foam, cartridge and BIOMAX are in place.\u003c\/p\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eRinse the foam block in tank water when flow slows or it looks clogged, and replace the Poly-Carb cartridge every 2 to 4 weeks — the carbon inside exhausts well before the cartridge looks dirty.
