I guess fertilizer would be OK for an intensely or maybe professionaly managed pond with a dependable water level.
I live 70 miles from my land and can't stay on top of things like I would like to. Also, my ponds are now 2/3 of the size they were prior to the drought. Had I fertilized, I would be in real trouble. I have good recruitment of BG and don't need any more. I tried fertilizing and saw 2 DO crashes in 2 years. Never again. Early this year, I had a four foot visibility. Later, after enough fish poop, I have about 18.
