Bill Cody wouldn't have any trouble calculating how much biomass I may have here. Assume an average size of 4.8 inches (there are LOTS of 4.25's), with a Wr of around 100 he might know what my weight for 150 gallons is. I get the sense by the general water quality that I'm nowhere near carrying capacity. Of course, you know me. I might just push it to the brink.
