Thanks for the info. George 1.

I thought my stocking schedule was about right, I just didn't when the CNBG population would have grown to the right numbers. I am a little surprised by the number of HSB you recomend, 100 seems like a lot for a 1/2 acre pond, but that's why I asked for help, because I was not sure. If i continue to feed the CNBG's will the HSB eventually start eating pellets or will they prefer the CNBG's if they are in big enough numbers? The pond is only about 6' deep at the deepest, probably 4' deep on average, and I surface aerate 24/7, and top off with well water. The pond tends to be low alkalinity, but have the opportunity to lime with liquid lime soon. I will add a small amount of lime to start and go at it slowly. Thanks again for in-put george I appreciate it.....................Budster
