Dymax Black Bio Sponge

Dymax Black Bio Sponge

Dymax Black Bio Sponge is a filter sponge for biological and mechanical filtration in both freshwater and marine aquariums. Supplied as a 32 x 12 cm (12.6" x 4.7") piece, it suits aquarists who want one reusable medium to hold beneficial bacteria and catch loose debris.

Key Benefits

• Works as both a biological and a mechanical filter medium, so one sponge does two jobs in your filter.
• Gives beneficial bacteria a site to settle on, which supports good water quality in the aquarium.
• Traps loose particles of debris as water passes through, helping to keep the water clear.
• Made from quality non-toxic material.
• Can be washed and re-used rather than thrown away.

How to Use

• Use it as a filter medium in your aquarium filter for biological and mechanical filtration.
• When it needs cleaning, rinse it in tank water, not tap water. This helps it keep working as a biological filter.
• After rinsing, the sponge can be put back into service and used again.
