Filtration Benefits
The Fluval AquaClear AC50 supports three common types of aquarium filtration. The foam insert helps collect debris and provides surface area for beneficial bacteria. Activated carbon can help remove some dissolved organics and discoloration. BioMax media provides additional surface area for biological filtration.
The open media basket gives aquarists flexibility to adjust media choices based on stocking level, water clarity needs, planted tank goals, or maintenance routine.
