Went to the local pool store to buy a new pump/sand filter for 18x32 in ground pool with average depth of 5.5 feet. I did let the salesman know that it was 8ft deep at one end and 3 at the other. They sold me a 26inch sand filter with 2hp pump branded Eco Kleer. We came home (haven’t even picked it up from warehouse) and everything online says that the pump is for above ground pools only. I’m guessing it is a pruning issue? What does the expert say? Will this work for my above ground pool or am I back to square one? Thanks in advance!!
