Best Filter Media for Planted Tanks (2026)
As an Amazon Associate I earn from qualifying purchases.
Filter media is what actually does the cleaning inside any filter, and it falls into three roles. Mechanical media traps floating debris, biological media houses the bacteria that convert ammonia and nitrite, and chemical media like activated carbon targets specific impurities and discoloration. A healthy planted tank generally leans on plenty of biological media, with mechanical media to keep the water polished and chemical media used selectively. Choosing media suits anyone setting up a new filter or looking to improve water clarity and stability in an existing one. Think about how much room your filter has, and prioritize a good volume of biological media since that is what keeps the tank cycled. In planted tanks, many keepers skip or limit carbon so it does not strip nutrients. If your water looks cloudy or your parameters swing, upgrading and arranging your media is often the fix.
