I have been using the Nitro bleach method for going on 6 months-still crystal clear water. ( I'm so glad I found you guys.) Anyway, thinking of changing water and wanted to know if their is a specific order in which to put in chemicals. I will be increasing calcium hardness, lowering total alkalinity, adding Gentle spa (borates) and of course diclor. I also will be installing a Nature 2 cartridge in an attempt to master the "low chlorine" recipe.(No MPS). Early on in my spa ownership I developed a rash which I was hoping was folliculitus (that can be fixed) but was determined by a visit to a dermatologist that it was simply excema,which is irritated by hot tub use. I have used the tub less with success although would really enjoy using it more. I also was going to change from dry acid to muratic acid as somewhere I read that it was less irritating than the dry acid. Any input or recommendations would be deeply appreciated.

Thanks to Chem Geek and Nitro I now have the best water quality my hot tub has ever had. Although.... I seem to have an issue regarding Chlorine demand. It seems as though the more we use the hot tub the less chlorine is required and when not used the chlorine use is excessive. I have read chlorine levels every day for the past two months,using a Taylor 2006, trying to get a handle on this and I am becoming more confused. As an example with a chlorine reading of 2.0 prior to a 30 minute soak and adding 3 ozs. bleach after the soak the following morning the Chlorine reading was still over 2.0. Not using the tub I can see a 50% or more chlorine demand in 24 hours. Is this normal with an ozonator. Should I shock the tub to see if I can get the CD down when we are not using? Confused.
