Last Post - Turns out that I had a severe dip in my line between the pump and the aerator. Those pumps are pulling in humid air and it's going underground which is cooler, causing condensation and I could hear water bubbling in my line. I found a spot to shorten my run and take out the dip and the same pump which struggled at 4' is easily doing 8-10' now. Took some digging, but I'm happy with the end result. Thanks for the help guys.
