I was looking at larger above ground pools recently and I was amazed that every one of them had one skimmer and one return coming though the same panel, not more than 2' from each other. I realize the logic for doing this has to do with the flexible hose lengths and having one stainless steel panel, but for the life of me I can not imagine how a 33' round pool or a 21' x 43' oval pool is ever going to get any kind of decent circulation with this setup. I'll bet you could run the pump all day and never really filter some of the water at the other end of the pool. I don't think anyone would dream of using one skimmer and one return on any in ground pool, so why is it acceptable for an above ground pool? Those of you who are installers out there, do you add additional return and/or skimmers to your AG installs? I've seen some sites that recommend instaling the returns on one side/end of the pool and placing the skimmer(s) on the other side/end of the pool. Logically this seems like it would be much more effective. What do you think?
