What kind of damage did you have? What kind of support did you have for the base?

If you're referring to a Kasco surface aerator I don't believe that is the route you want to go in a pond of your depth. You'll be better served with a compressor and a bottom diffuser(s) and it will probably be cheaper too!

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
