I have been reading some of these posts and I am really confused on what my water chemistry should be. I bought a 375 gallon Kona Artesian spa with the frog in-line mineral/smart-Chlor and an ozonator back in April and I’ve been frustrated ever since.
The set-up guy told us how many capfuls of what leisure time chemicals to use each week and which test strips to use. I ended up with the hot tub rash after about a month 😢 Did the leisure time jet cleaner purge thing, drained it, filled it with filtered water and started all over. A couple weeks laterI got the rash again!
Started reading here and we did an ahh-some purge 2x and I am using hot tub serum once a week. There was a bit of funk the 1st purge, second was ok. Now the total chlorine has been higher (10ppm) but I also use MPS and dichlor after each use. Maybe that and the ozonator making that a false high? (I know after CYA gets too high I should switch to a regular non-scented bleach)
Trying to figure out where the free chlorine level should be with all the other stuff going on in this tub. After the hot tub rash, I have been trying to keep it close to 5ppm, but maybe that’s too high with the smart chlor/mineral/ozonator?
I’m trying to follow how all the other things relate but have not quite grasped it yet. Any thoughts? All other readings are in the ideal range. I’m now using a Taylor K2005 year kit.
thanks for any help!!
