[QUOTE="Deer Slayer, post: 1569780, member: 8855"] Ok, fellas Perplexed is 100% correct. I have had a call or two regarding ponds dying. I have designed and installed several aeration systems for ponds, most notably, the"close to Home" fisheries for the ODWC in Oklahoma City. The problem is that there is insufficient wind action to provide oxygen transfer plus hot water holds little oxygen. Fish need a minimum of 5 ppm of DO to survive and at 3 ppm they are stressed. The pond will crash between 5:00 am and 7:00am because, over the night, the DO has been consumed and we have a domino effect with fish dying and ammonia levels rising. Perplexed - You gave an excellant explanation.WTG:woohoo1: I use a subsurface aeration system that will pump/mix/aerate 200,000 +gallons/day/unit and is economical to run during the summer. I typically suggest to pond owners to run them during July,August and September and Mother Nature does the rest. There are some other tricks that help ponds too that I suggest to owners when I am consulting with them. I am a water and wastewater consultant and help manage millions of gallons of sewage for municipalities in several states. [/QUOTE]
