Hey all, I know NOTHING about hot tubs/spa's as I don't have one..but my brother does. He was recently talked into converting his 500 gallon hot tub over to something called "soft soak"...I guess it's a hydrogen peroxide type of product ??????
Anyway..he hates it, and he says there is always a greyish sludge on his waterline, and he wants to switch back to either Bromine or Chlorine.
I told him I'd post to the forum here, as I know you guys won't steer him wrong. How does he convert back, or does he DRAIN it all out..clean the tub and then refill with water and start over from fresh?? He has new filters he can put in too, to replace the old ones.
Any help/advice would be much appreciated.
