Construction will begin soon, so I can't answer the plankton bloom question. The pond will be about 1 acre, with depth of about 20' at the dam, so average depth about 12' I'd guess. Will stock with LM and BG, and will manage for size as opposed to numbers. Will also stock FH minnows. I like the ability to increase the pond's carrying capacity, but I wasn't sure what it dod to the BG foodsource of plankton. I guess managing for trophy fish might also mean I won't need as high a carrying capacity??? I've read so much on aeration I think I'm even more confused now. Thanks for the input.
