Is an 18 foot ultra frame pool and Hayward power flo lx pump a good combination? We have the pump from a total pool fail (I'd rather not talk about it. ) We are considering buying the 18 foot or 22 foot ultra frame pool and everyone suggests a pump upgrade. Since we have this one I thought it would be easiest to use it. Any tips, advice, help is much appreciated as I have no idea what I'm doing.
