I have heard alot of good things about the Gast pumps you mentioned in terms of reliability and durabilty. I'm trying to understand the size of pump needed per given depth of water and how that's determined. And is bigger then that actually better or does the output plateau and the rest is just overkill?
I would rely strictly on Bill Cody's advice on Gast pumps - size of pump needed per given depth of water and how that's determined.
His first response wll be, "It all depends"
