New development.
I hooked up one of my Vertex diffusers and lowered it on the 7ft side. My psi gauge then went up to 10psi and the relief valve was going off.
I disconnected it and went back to the old stick/stone diffuser and it drops down to 6psi which is still higher than the 3psi it was running before. Not sure what changed.
Any thoughts?
I did add drain the pond down about 3ft due to the fish kill so I can clean up some cattails and added some fluridone and blue uv dye to try to take care of some of the curly pond weed. Can't imagine any of this would cause an issue.
