I'm setting up a 150 gal FOWLR DT, in which I would like to have a large angel, greebird wrasse, puffer, naso tang, and trigger. I know they like a lot of swimming space. I have about 150 lb LR in the DT and some in a refuge, but I'd rather not put any more in the DT because it will cut down on the swimming room. Any suggestions on what I can add to increase my bioload? Thank you.
