Sponge filters provide both mechanical and biological filtration using an air line for gentle, safe filtration for fry tanks. Simply attach an airline to the unit and provide both aeration and filtration to your tank. Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle. The sponge traps larger waste particles mechanically cleaning the water without trapping baby fish. This is a must have for clownfish fry tanks once the clownfish morph and begin to eat flake food, but are still too small for a regular filter. The air hose you are currently using to provide oxygen to the fry tank can be replaced with this sponge filter, all you do is attach the airline right to the unit. The air bubbles come out of the top nozzle, which is completely adjustable allowing you to choose the direction of the flow. The nozzle height is also adjustable.
The product size is 5x5 1/2 inches and can easily fit in a 10 gallon tank with the water filled 3/4 full. If you currently have the 10 gallon filled halfway, just add a couple more gallons. Having one of these in your fry tank also reduces the amount of water changes you have to do, or reduces the amount of water you change per day. If you would like to keep your morphed fry in the 10 gallon and wish to convert it into a fully cycled tank, begin by placing the foam filter in the parent tank for a week. This will seed the filter with healthy bacteria. You can then add it to your fry tank for easy conversion.
Note: The air pump and air line is NOT included. You must provide your own air pump.
