I'm in the process of getting quotes for my third pool. After every pool you learn something you want to avoid next time and you also know things you want to add or change. This time I want to have a SWG to avoid the pleasures of dealing with bleach. One pool builder has recommended his best SWG system and I'm not sure what it totally is. He wants to put in a Mineral Springs System. I know that it does consist of a Goldline SWG but adds other things to the water. When I asked what they were he stated that they are other things I needed to balance my pool water. I've been testing my water for years and making the adjustments using BBB and advise from this site and my pools have looked great. Obviously I have not had the need for these other things in my pool. Can someone explain this Mineral Springs system and why I would need it or want it?
Thanks for any light you can shed on this issue.
