Fish Crazy
I have an external canister filter that came with my Amazon 240 tank (same as Jeuwl I belive?)
Inside it right now is some white porus type of clay? pieces, black bio balls and some blue and white foam I belive.
Do I need to change this, ive read lots about carbon? what does this do? Cheers.
