Another thread. About 5 or 6 posts down the page I have some pictures of DUAL Matala diffusers. I use 2 disks in the main 3 acre pond and a single in each of the 1/20th acre forage pond and 1/10th acre sediment pond .

When I was driving each dual with an individual diaphragm pump on occasion one disk would stick shut and only be putting air out one disk. I was at the low end of CFM specs.

When I switched to a big vane pump I now drive all the diffusers, 3 doubles and 2 singles for a total of 8 disks. I have not had that issue since.

A discussion of some of this in that thread.

Just an FYI.

I think Vertex is the preferred brand of diffuser here on PBF, but the Matalas have seemed to do the job. Don't really know if something else would have been better.
