I have a 3/4 acre pond that is 7 ft deep and has bass and a few bream. It is about 19 years old and has never been taken care of. I want to start with aeration but after reading this I may wait until fall to start since I am just south of Houston, Tx Should I try some bacteria this summer to help a little or what to start getting the bottom muck taken care of. Also where is best place to get info on aeration systems and needed flow rates?
