I think it's Curly Leaf but not 100% sure. It is that type anyhow.
I just installed a pressure gauge at the compressor and it is reading 3psi. If I stop the flow by pinching off the hose for a second it jumps over 30psi. Not sure how to understand the pressure ratings. The pump is 4.5cfm open flow I believe.
I talked to Ted Lea today and will be ordering a pair of single disc Vertex diffusers. One for each side of the pond.
