I have 3000gph on a 540 with a 150 gallon sump and a 44gallon bio chamber.

The bio chamber is actually the filter. The mechanical is "Old Fashion Needle Punch Batting" that I get from Walmart (I hate Walmart, but don't know where else to get it). Underneath that are a several hundred plastic pot scrubbers.
