I'm about to go pick up the 2 SWFs I ordered for my divided 6. I think the filters come with carbon in them and I'd rather just take that out from the get go and put something else in it.... but what?
I really don't have the extra cash to go buy some high falutin' filter stuff and I was wondering if cotton balls or a piece of sponge like this
I already have the air hose and air pump and I'll be cloning the filters with gravel borrowed from other tanks. I could put pieces of the sponge in my established filters for a couple days then transfer them to the SWFs if I can get the sponge to go in the SWF.
