Powkoo Air Pump Sponge Filter Bio Filter for Aquarium Fish Tank Up to 60 Gallons

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
