I am going to have my first pool installed this spring and I do NOT want a chlorine based pool. The salesperson at the pool store is recommending permasalt to me, which I believe is an ionization system. Now after reading this thread I know the users on this forum do not like ionizers. I am not for nor against them, as I know nothing about them. My question to you all is, which would you recommend if you don't want an ionizer but wanted to avoid chlorine? What about saltwater? Are there strong opinions on a saltwater system? I don't mind shocking my pool with chlorine to keep the bacteria out but I want the base to be something other than chlorine. Thoughts?
