Right now there is nothing living in my pond aside from frogs, turtles, and bugs. It's about 5000-6000 SF and varies in depth from 6" to 5' with probably a good 12" or more of muck in the deepest part. I have a ton of work to do around the pond as well as in the pond (removing aquatic weeds, etc...) and there is no way I would stock it with anything until next spring at the very earliest. That said, should I be aerating 24/7 now to try to release the H2S and break down the muck since I don't have to worry about a fish kill? What about manual removal? Because of where it is on my property/in the woods heavy equipment is not an option, but I've thought about trying to suck some areas out with a trash pump. Basically, what would you do with your pond if you didn't have to worry about keeping fish alive while you were doing it?
