Ultra quiet for a small fish tank
This small fish tank filter is driven by an air pump, it is so quiet that you can only hear the beautiful sound of bubbles bursting on the water’s surface.
A 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 the water. Slow water flow is great for betta fish, snails, and shrimp.
Easy to replace the filter cartridge
The filter cartridge contains activated carbon to remove odors, fish waste, and other impurities, while a white dense pad traps large particles in the tank. You can replace the filter cartridge every 2 to 4 weeks or as needed.
