Welcome to our forum.
where can I find out what the Vermonter method is that is mentioned.Also, what is CYA and how do you test for CYA?Tony
Because of my reaction to MPS, I have to shock with dichlor. I know that liquid bleach is an option, but I just don't want to go that route. So my question is, how does the germ that causes hot tub itch get into a personal spa? If it's just myself and my husband using it and no suits are involved, do I need to worry about it?
Fwiw, I can keep my CYA under 100ppm for 3+ months. Mostly due to the fact that I'm pretty much the only bather and therefore my dichlor doses are minimal. But I also think using a N2 catridge along with an ozonator and using mps instead of dichlor to prevent chloramines helps alot too. Oh yeah, I try and keep my pH between 7.2 and 7.4 as well so that my dichlor doses will be a higher percentage of hypochlorus acid(the killing form of chlorine). This maximizes the sanitizing capabilities of each dose.
