I like the idea of a box filter as an additional filter. I'm sure this is a stupid question. I realize that I can regulate the air output of the pump which increases or decreases flow, but how can I approximate the flow rate through the media. I'm trying to increase anaerobic BB and I was going to put Denitrate in it and wanted to keep flow rate below 50 gph. So I guess I am asking what 50 gph output of bubbles look like? I feel idiotic asking this.
