oh, and to answer your question, yes, you should leave some media in the existing filter, unless you are running two filters, or have lots of porous rock/surface area in your tank that would house enough BB to support your bio-load.

I was getting that impression about the filter media, but hadn't tracked down the specifics yet. Like quilt batting? Wool or poly? I am guessing cotton would be a gunky mess pretty quickly. What would be the bio media options for an aqueon quietflow filter? I guess the aquaclear makes more sense in that regard. The aqueon seems a little less obvious.
So our cycled tank is a 15 with an aqueon quietflow 30 filter. It has 10 fish, driftwood, two vals, some spreading java fern and a rapidly reproducing clump of java moss. We do a pwc (35% ish) sometimes every week, but sometimes every other. What is the (loose ballpark) estimate for the life of that filter? What sorts of things indicate the need for a change?
Thanks for all the info!
