Hi, I did a quick search but don't see the answer to this. I have a costco bestway pool with the sandfilter, and I have an older krystal clear Intex saltwater chlorinator. The hose that goes between them requires a nut on each end, however the intex has the 40mm threads while the bestway doesn't. So I need a hose with two different ends, basically. Since the both machines have a thread external entry (not threads on the inside of the entry, the intex adapter doesn't work. I can't find a solution, please help.
