Hey guys I'm currently in the process of building an overflow and trickle/tower filter for my 55 gallon. I bought the tank in one of those package deals and i wasn't really blown away by the filtration, so now i'm making my own. I want to know what kind of filter media i should use that would grow the best beneficial bacteria for my tank. I want it to be as cost effective as possible. Any Ideas or experiences would be appreciated.
