Round Aquarium Sponge Filter ZOOLOGIA GĄBKA OKRĄGŁA 12/7

ZOOLOGIA GĄBKA OKRĄGŁA 12/7 is a round aquarium sponge designed to perform mechanical and biological filtration in small to medium aquaria. The open-cell foam traps suspended debris and provides a porous surface for colonization by nitrifying bacteria, supporting stable water parameters. Its compact circular shape fits common internal filter housings, sponge filters and some external filter baskets, and the durable foam tolerates regular rinsing and reuse.

Advantages

The sponge combines efficient mechanical debris removal with a high surface area for beneficial bacteria, improving water clarity and biological filtration without introducing chemicals. Its resilient foam construction resists tearing during cleaning and maintains shape over repeated use. The round design facilitates easy placement and even flow distribution in compatible filter housings.

Suitable for

• Mechanical filtration in small and medium freshwater aquariums
• Biological filtration and bacterial colonization
• Use inside internal filter housings, sponge filters and filter baskets
• Temporary filtration during maintenance or as a replacement element

Key specifications

• Shape: round
• Function: mechanical and biological filtration
• Material: open-cell foam
• Compatibility: suitable for internal filters, sponge filters and many external filter baskets (check dimensions)
• Intended aquarium size: small to medium setups

How to use

Rinse the sponge thoroughly in dechlorinated water or aquarium water before first installation to remove production residues. Insert the sponge into the filter housing or sponge filter so that water flows evenly through the foam. Monitor flow and water clarity regularly and inspect the sponge for clogging. When mechanical debris builds up, rinse the sponge gently in a bucket of aquarium water until debris is released; avoid using tap water with chlorine. Replace the sponge when it becomes misshapen or permanently clogged and cannot be restored by rinsing.

Usage recommendations

For stable biological filtration, avoid replacing all filtration media at the same time; stagger replacements and perform partial rinses in aquarium water to preserve beneficial bacterial colonies. Verify sponge dimensions against your filter housing before purchase to ensure proper fit.
