I was wondering if my AC500, Powerhead at 214GPH (just for a small current) and a BioWheel 200 rated for 50 Gallons. I have another AC500 not being used. Should i switch out the BioWheel for the other AC500?
I'm going to guess that since they have cutesie names & you didn't post their size, that they are still small. That setup will do fine if thats the case...if not then double up the filters and use only bio-media in one with a pre-filter.
Are you experiencing prob.s with the water chemistry now?
