Pond Boss Forums AERATION Systems questions Cut plastic 55gal drum in half for aerator base?

I assume you also intend to drill holes in the half barrel to allow water to fill and drain from the containment? If you dont drill holes, pulling the diffuser for maintenance and cleaning would be quite a chore once you got it to the surface.

I imagine such a setup would reduce the amount of sediment being disturbed.

What kind of visibility do you have now? A certain amount of disturbance is needed to create enough turbidity to reduce sunlight penetration and help keep deep water cooler (unless you're running 24/7). It's also been stated that disturbing the bottom helps to expedite the reduction of muck.

It's been my experience that my turbidity clears up after a week or so from starting my bottom aeration.
