I have a 22' Intex ultra frame pool. I upgraded to a 16" sand filter combined with a saltwater system. The pool came with a vacuum head for the skimmer pole, but no hose. I purchased a vacuum hose - HTH Universal. The problem is, I have no idea how to attach it to the filter. It may be obvious, but I'm just not seeing anywhere that the hose will fit. I have attempted to search the internet and forum for this answer, but I'm not finding anything specific. Do I need a connector? Any help would be greatly appreciated. The clean, clear water is not so pretty with sediment on the pool floor.
