Filtration

Filtration in a planted tank does two jobs: it keeps water clear and it moves CO2 and nutrients to every leaf. Dead spots are where algae starts.

Canister filters, stainless steel filters, sponge filters, surface skimmers, media and replacement parts — sized for nano cubes through 120-gallon showpieces.

Sizing: aim for 5–10× tank volume in turnover per hour on a planted scape.
