Sponges and Ceramic Blocks in Canister

[xkornstarx2]

I've heard many conflicting opinions about use of sponges and ceramic things in filters because they become nitrate(?) factories if not kept clean.....I have a 10g tank that is currently cycling with 19lbs of LR and 20lbs LS...should i keep them in the filter or just keep the carbon in there??
