So it's probably too late for this year - but I think I do want to add another return - but how does that work? I'm asssuming you'd want it on the other end of the pool (we have a 21x41 aboveground pool) because that end doesn't seem to get much action!
Do you just put a whole nother filter/pump set up down there? Or run a line all the way from the pump/filter at the other end?
If anyone can tell me about multiple returns, I'd appreciate it. I did a search and didn't come up with anything.
