Biochemical Sponge Filter - Serenity

Serenity Biochemical Sponge Filters build up a colony of beneficial bacteria that break down ammonia and nitrite as water is drawn through the sponge, while also trapping detritus to keep the tank clean. Air lifts the water through the foam, so the filter oxygenates as it works.

Gentle flow and no exposed intake make them a favourite for shrimp, fry, breeding, betta and quarantine tanks, or as a backup filter.
