First off I have an AG pool (18' x 48" Summer Waves just bought last week). Last year we had another AG pool (the liner ended up tearing so we bought a new pool). My son had some skin issues when swimming and we believe it was related to the chlorine. So we've been looking at getting a Salt water filter.
I talked to my friend who has a Salt Water filter and he told me that in Michigan the salt ionizer does not work as well because it doesn't get hot enough.
I'm very new to this so I'm wondering if there are other types of Salt water filter that don't use the ionizer? I found one on Amazon that has E.C.O. (Electrocatalytic Oxidation) is that the same thing?
Also, I know I will need another filter along with the SWG, would it be OK to use a cartridge filter or would you suggest a Sand filter?
Thanks for all your help.
