Just got back from Todd's place yesterday with 500 CNB 100 RES and 10 lb of fhm. It was cold and raining when I got there. My question and one I should have ask but did not think about it until today. My pond was built in May of this year and it is about 3/8 acre. My goal is to have large CNB. Question is when do I start feeding them and what should I use. Plan on putting in 50 HSB this spring or should I wait until fall of 2014.
