Pond Boss Forums AERATION Systems questions What type of diffusor?

Here is the same Matala 9" diffuser on a home made base. I use one of these in my sediment pond (1/10th acre)and one in my forage pond (1/20th acre).

One mistake is that the small footprint tends to sink into a muddy bottom. I intend to swim out and set them in a plastic concrete mixing tub to keep them up a little higher. If I was doing it again, I would figure out a way of making a larger footprint for the base. It has not been a problem in my forage pond, but I have seen it create some turbidity from stirring up sediment in my sediment pond. It goes away after whatever mud around the diffuser gets distributed away from it, but it would be better if it set up off the bottom a little more.
