This is probably the wrong place to post this but I wanted to check and see if anyone had any experience with "mineral systems"? PB says that they are "awesome"... requires less chlorine, so it is easier on your skin but also "easier" to maintain than SWG systems? I know SWG are supposedly easy already but they state that when they get out of wack that they are harder to get back right, whereas the mineral system is just easier... I am confused. PB makes them sound great and says that they almost entirely use the mineral systems on all their pools now 9:1 mineral vs SWG pools? Are they that good?
