    I finally found the right filter!

    By DanaD on Aug 5, 2019

    I have a 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.

    Starter kit

    By 2HelpBull on Nov 12, 2019

    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.

    Filter clean

    By on

    This is not what I expected. It says it would keep the tank sparkling clear for a month, well it stayed that way for about two weeks. My home made filters last longer them. Some people may like them but I don’t.
