I purchased a Maxx 471 with a clean zone ll system because I thought I would be using less chemicals, it doesn't seem to be the case, I have been using Ho2o instead of Bromine, is there a way to tell if my clean zone is working correctly besides just that the light is on as the technition has told us. I had switched to Ho2o because I could not stand the smell of all the bromine I had to put in the tub I had only had the tub 2 months before switching over.
