Tony, you mention N2 being a slow, low level sanitizer, do you believe it can kill the psued. germ? I know some people use nothing but N2 and MPS, which we all know is not a sanitizer. I'm like Boni and was totally freaked out about the whole psued. thing. I got bumps that looked just like it and PANICKED. I was ready to give up the whole spa thing. Luckily, my brother-in-law is an allergist and I found out it was the MPS I was shocking with. PHEW.
