About this product
Four medium ALEGI aquarium sponge filters make up this pack, and each one is recommended for a 20-50 gallon tank. Every unit gives mechanical and biological filtration. The set also has four check valves, four control valves and four suction cups.
Rinsing the sponge keeps the setup going
The sponge is cleaned by rinsing and squeezing it in tank water.
Hooked to an air pump, the unit carries an airline down into the tank through the top.

What the four-piece set includes
- Four medium sponge filters
- Four non-return check valves
- Four control valves
- Four suction cups
Installing the sponge filter with an air pump
An air hose runs from the air pump to the filter, and the pump then switches on. Setup and cleaning both happen from the top of the unit.
The check valve on the air hose stops water from flowing back and protects the air pump from damage if the power goes out.
Questions about the sponge filter set
How big a tank is one filter rated for?
Each sponge filter is recommended for a 20-50 gallon tank, so four filters cover four tanks at that range.
What is in the pack?
The pack holds four sponge filters, four non-return check valves, four control valves and four suction cups.
How do I connect the filter to the air pump?
Attach one end of an air hose to the air pump and the other end to the filter, then turn the pump on.
How is the sponge cleaned?
Rinse and squeeze the sponge in tank water.
What does the check valve do?
A check valve sits on the air hose to keep water from flowing back and to protect the air pump if the power fails.
How the filters work in the tank
The medium size runs air through a sponge that provides mechanical and biological filtration. Airflow from the pump is set with a control valve on the hose, and a suction cup holds the unit in place inside the tank.
Installation takes one airline: the hose goes into the top of the unit, and the air pump is turned on.
