Ok so now I am making for structure by taking 5 gallon buckets and drilling holes and sticking flexible pvc pipe in it. Going good so far. I am going to do five buckets. Also we are putting in 50 CC 8-11in, 350 bluegill 3-4in and 2000 minnows. I am wondering I am building the structure for the bluegill do I need to add anymore for the CC? I already have two 15ft tubes in the pond do I need to add anymore?
