I have a pond that is .4 of an acre and it is burmed all the way around so there is nothing that can run into or out of my pond. I use an aerator that has 2 round soaker hose type diffusers. My pond is 12' deep and diffusers are set at 8'. I have been running them 24/7 for the past year. I haven't had any dead fish that I can see. Is this a bad idea to be running them this long? I don't have much algae buildup and as far as I can tell my fish are ok. I have small mouth, bluegill and CC in the pond.
