our pool is the 14x14 square intex pool. It came with the tiny 1.25 hoses and a terrible little filter pump that did not work. The pool has three holes for hoses two in and one out. I just bought a sand filter it takes bigger hoses 1.5 so I have seen others just cut the holes bigger to adjust, planning on doing that but my new pump only has two hoses what should i do with the third hole in the pool is there some type of plug or something to close it off,. Does any of this even make sense with no pictures
