That is exactly why I have not pulled the trigger and bought an aeration system for our 6.5 acre BOW (60+ years old). I will certainly see the same sediment problem happening if I put diffusers on the bottom.....or very close to the bottom. Probably a foot of muck on the bottom of my old BOW....that would be a pure guess based on wading the shallower areas.
I need to figure out how to get the diffusers as close to the bottom as possible without disturbing the muck....that is the last thing I want to occur after dropping a good chunk of change on an aeration system.....I don't need permanently cloudy/muddy/mucky water. Maybe the 12-18 inch height off the bottom is actually about right??
Thinking of constructing a PVC "box"....18 inches high....that the diffuser would sit on. Maybe even add some sort of "pan" between the PVC box and the diffuser.
Hope you can find a solution to what has to be a totally frustrating problem millinghill. BM61
