Highlighted Reviews
"I have an internal filter pump for one of my small tanks. I could never find the right filter media and tried 4 or 5 different ones but the pump never ran right. Finally, I stumbled upon these. They fit perfectly and work wonderful."
"This filter came with the acrylic 5G starter kit, the filter cartridge is fine, but does not keep water clear unless you continuously change it, hard to establish biological stability, if at all."
Bottom Line
This filter is a reasonable choice for smaller aquariums, but be prepared to replace it more frequently than expected.
