I've had a good few filters over the last couple of years and have spent a few quid getting new filter wool , foam and bio ring etc when I'm setting up a new tank . Just wondering is it possible just to buy sheets of filter foam and wool that I can just chop up myself and is there an aquarium safe type that I should be using. Also is it possible to create some sort of media that would replicate what bio rings do.
I had bought a sheet of floss wool stuff from the local lfs this time last year and managed to keep me going all year. What exactly is this material.
