Bio Sponge – L-sized sponge

This sponge insert from Happet is designed for aquarium keepers who see debris accumulating and ammonia, nitrites or nitrates rising in their tank. It works as a single filter medium that handles both particle removal and biological processing, so it can be placed in the filtration system without a separate stage for each function.

Why it matters

• Combines mechanical and biological filtration in one medium, so trapping particles and supporting beneficial bacteria happen in the same insert.
• Targets the three nitrogen compounds named in the product description: ammonia, nitrites and nitrates, which can quickly disturb the biological balance of a tank.
• Removes accumulated contaminants from the water, which the manufacturer identifies as a common problem for aquarists.
• Supplied in size L, selected to suit the larger of the available sponge formats.
