Driven by air pump, it is so quiet that you can only hear the beautiful sound of bubble bursting in the water surface.
Mechanical pre-filter sponge captures debris and activates carbon for clean and clear aquarium water. Mini white bubbler stone produces constant and soft bubbles to agitate water. Slow water flow is great for betta fish, fry, and shrimp.
Compact fish tank filter
Single small filter measures 4.1″ x 0.8″ x 7.6″, and is recommended for 2-5 gallons fresh and salt water aquariums.

Directions for Use
Step 1: Rinse the filter cartridge and all parts with clean water from tank in order to remove the debris and dust, and clean the filter.
Step 2: Put the filter cartridge into filter. Make sure the filter cartridge is in the card slot.
Step 3: Rotate the upper elbow to adjust the direction of airvent.
Step 4: Place the filter on the wall of aquarium with two suction cups or mount the hook to hang over. Hook’s height can be adjusted according to the water level.
