I have a 3 acre pond in central Georgia. I wanna throw in my 2 cents about fertilizing and feeding.
My pond drains a HUGE watershed and has water flowing through it most of the year. I have tried fertilizing and the water never stays in the pond long enough to achieve a bloom.
Greg Grimes has visited my pond on a couple of occasions and discussed this with me. We decided on a feeding program to feed the coppernose BG as a partial offset to not fertilizing. I have 3 Stren feeders and have them going three times a day now that temps are in the 70's.
So another reason NOT to fertilize - high water flow.
Just my 2 cents..
