"I know nothing"

I would stock my favorite CNBG. I would also begin doing RWs of the CC & LMB, removing those <90% till they are consistently 90% or more. Keep records! You will have to restock the CC. Your goal is a CC pond? IMO, isn't worth much, you overstocked both LMB & CC for a Qtr. acre pond.

Wait for the experts to put in their 2 cents, much more value than mine.
