Along the bottom perimeter of the intex pools is a seam. Most of my pool at least is pretty neatly done, but there are a few areas where there is excess material forming a flap of liner that traps stuff under it. No matter how much you go over it with a pool brush, some parts are really tight and will not flip over. I was SLAMing for about three weeks and couldn't figure out what was holding the water back from getting clear. After one week, it was a slightly hazy blue with a smidge of green. Two weeks later, still the same. Morning and night chem checks. Daily vacuum and brush, but still had that "is it dirt/pollen or is it algae brown "dust"" at the bottom. There were times where I thought I was making headway, but the next morning or the evening, would have it everywhere again. I even vac'd the pool to waste a several times with no luck. I started thinking about the flaps some more. I bought a $1.97 floor broom at walmart. Jammed it into the flap with a sweeping motion along the whole perimeter also trying to flip the flap over. There was about a two foot section that had algae guts spewing out. Low and behold, the pool cleared up in about 24 hours after I did this. Don't forget about those flaps. Next time I drain my pool, I'm going to cut the excess off the bad spots. I've gotten pretty comfortable with keeping a pool and me and my wife want more. I've been trying to design pools in solidworks that me and the wife agree on. Plan to build a concrete block pool much like Dave's, but probably in the 18x38 - 20x40 range.
Hope this helps someone.
