I have an 18 x 38 above ground with a 7 ft deep end. It was installed with a Doughboy AquaView 0-1709-020 2 sq ft sand filter and the pump is a Doughboy Powerline XP 1.5 HP. Ever since I installed the pool, I have always wondered if I should have another skimmer and filter/pump installed. The reason I wonder this is because I have very little wind protection and it seems like debris settles on one end or the other length wise. Maybe it is circulating properly but sometimes I wonder.
