Features:
The arms holding the sponges are adjustable to position the sponges better away from the tank walls. This filter is perfect for tanks housing baby fry or shrimp as they will not get sucked up and have a food source to eat off the sponge. Efficient product for the price and some fish will enjoy the decreased current in the tank.
The nozzle is adjustable which means you can point the flow toward the side of the tank to lessen it if you wish
Sponge filters provide both mechanical and biological filtration
Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle
In addition, the sponge traps larger waste particles mechanically cleaning the water without trapping baby fish
They are useful for as breeding filter or as secondary filter
Or they can be used as pre-filtration unit by fitting to an external or a top filter

Package Includes:
1 x Air Pump Double Sponge Water Filter for Aquarium
