Hi all, simple question that will probably have lots of answers but I appreciate everyone's opinion, thanks in advance:
20'x40' rectangle, 10' deep for about 30' length w/sloping sides, 3.5' deep for the remaining 10' length. Two return jets are on the shallow end-wall near the corners pointing toward the deep end, third return jet is in a deep end corner on the long wall. Skimmer is in the other deep end corner on the long wall, floor drain is at the bottom of the deep end (duh, ha). I keep both the floor and skimmer valves all the way open (unless I'm vacuuming). I have the largest eyeballs in the returns, figuring the more flow the better the circulation (the pump has no trouble feeding them enough to "jet")...which leads to my question:
Is it best to have the eyeballs pointing a bit toward their neighboring wall and very, very slightly up to create surface circulation for the skimmer (and a bit of aeration)? Or slightly down to create rotation a foot or so down (and the surface will follow the underlying current)? I want to make the best of what I have, my limited common sense makes me think the skimmer isn't in the best location; but other opinions (pool stores etc) are that the builder is one of the best in SW Michigan so I assume that the design is good. It does skim fairly well but I think it could do better...fortunately it's at the far end where the usually prevailing WSW breeze pushes the surface "stuff" (cottonwood seeds this week) but I want to make sure the eyeballs are pointed for optimal circulation of the dive tank as well as skimming. I've experimented moving them different ways the past nine years but wondered if there's a good rule of thumb (or even a definitive answer, ha)?
Maybe I should have taken a picture, ha...nightime now though. Thanks again in advance.
