I finally have my ground level and pavers laid out for pool ready for sand. I have a bestway 22x52 round pool. I plan to go ahead and upgrade to the intex sand filter and saltwater generator but a question......Are the fittings the same? I assumed everything would go right together but am I going to need to rig the fittings to make it work? I seen youtube comments some saying they are the same fittings and nothing extra is needed and one guy on there had to buy different fittings. Someone who knows for sure? Thank you in advance
