How does a bio sponge filter work?
Attached a sponge filter to a 3/16 inch airline to an air pump( at least 2w), constant flow of air bubbles rise up from the top and out into fish tank.Dirty water be sucked into small fish filter through chink, fine sponge traps fish waste, decaying plants and other debris, while bio balls provide plenty space areas for the colony of beneficial bacteia to thrive and grow, and finally push clean water out of the top of the filter. Thanks to both mechanial and biological filtrations, this small yet efficient filter filtered out sparkly clean water. At the meantime, it agitates water surface with constant bubbles.
