Currently have a ultra 16 x 48 with a krystal clear saltwater with copper pump filter, but am thinking about upgrading to a hayward sand filter and separate pump. Would I benefit from this and how do you get the standard hoses that come with sand filters non intex to mate with the pool? Am also wanting to add a through wall skimmer is there any write up detailing the sand filter hook up I have found one for the skimmer . Thanks
