Thanks for your ideas. We have cut back on feeding and my husband has hooked up the boat motor for some extra agitation. Caught one CC yesterday that was about 2 lbs. Looked healthy. I think we are going to have all the nieces/nephews, aunts/uncles over for a big fish catching event and have a family fish fry. Try to lower the population to less than 100. Then do the same in the spring, maybe get it down to 50.
The pond is for fun, future grandchildren, etc.
So we got to be able to feed them!
What would you consider the 'best' aeration 'system'. Both a bottom diffuser and a top water circulator?
