Have an INTEX 12 x 24 XTR Pool and I bought a Saltwater System and a Hayward Skimmer as add-ons. The instructions with the Hayward Skimmer are horrible and I’m unclear as to where to hook it up to the system. I’ve been running the system to clean the pool without the skimmer hooked up thus far and I’m not sure what hose that’s currently in the system should no longer be used? Any help would be greatly appreciated.
