Fry Sponge Filters
Fish friendly sponge filters, commonly referred to as fry filters, are typically air driven. They are particularly coveted by breeders or keepers of small fish and fry that may otherwise be harmed or vulnerable to traditional filter inlets.
The large surface area provided by the sponge allows for effective mechanical filtration and the cultivation of beneficial bacteria, with the air-driven operation producing bubbles to oxygenate aquarium water. Sponge filters also serve effectively as inlets for powerhead pumps and external filters.
