new member here, i am building a new pool, rather large by most 18x73 (key hole shaped) approx 1250 sq ft of surface area. i am totally torn by the decision to go with SWG or N 2 system...i hav friends who have both and i must admit they all have nice water feel, clarity, so on and so on. but i guess my question is long term, these friends have not had their pools for 5 plus yrs or longer. what are the long term affects and what is the annual cost of products to maintain these systems?
i guess need a nice pros & cons chart to help me decide.
