If you use small LMB ,2-3 inches in size, it will be ok to add them in the fall. I would add a few FH just to remove the uncertainty. FH are cheap. The rate for CNBG is ok to low (500 is normal for 1/2 acre). The rate for CC is high. CC can add to the muddy condition. The alkalinity is in ppm and 95 is good. I would put no more than 50 2-3in. LMB in this fall (35-40 would be better) and start taking out some CC. Are you feeding the fish? This post assumes that you are not feeding. I think I would add another 250 2 in. CNBG/RES mix. Often from the hatchery CNBG and RES at that size will be mixed 80% CNBG and 20% RES.
