I pulled the Vertex diffusers and went back to the old stone diffusers on both lines and psi is back to normal about 5psi. Unfortunately with the weather I am not sure when I will be able to get the Vertex ones hooked back up to see what is going on.
As long as I know the Vertex diffusers can handle the output of the compressor I have then I will start looking at other potential issues.
Hopefully tomorrow I can experiment some and see what I can figure out.
I am pretty sure the line wasn't kinked. It is all new, self sinking line and was tight when lowered into the water.
Thanks for the info. I'll keep you all informed.
