filter media question
I have 2 Emporer 400's going into my 80G bowfront and I was curious on what I should use for filters. Obviously the bio-wheels will stay, but after too much reading I'm getting the impression that the blue carbon filters are pretty much useless. I've been told I should replace those with a sponge filters and if I see the need for carbon I should just use one of the refillable cartridges.
So I guess my questions are any of this accurate? how do you guys set up your filters? What do you use in the refillable cartridges?
