Hi Silverbullet,
I’m the fellow who is using hydrogen peroxide. Both my wife and I really like it. It’s easy to use and there is no dry skin or chemical smell. I wouldn’t go so far as to say it moisturizes the skin, but it really does have a nice feel to it. You should also understand however that hydrogen peroxide is not approved for use in hot tubs in either Canada or the U.S. I understand that it is approved in Australia for what that’s worth.
We originally started using hydrogen peroxide because my wife has some pretty serious chemical sensitivities and we wanted to find an alternative to bromine or chlorine. I think now that we have tried it, we would have used it even if she didn’t have the chemical sensitivities. If you would like any further information, feel free to PM me and I’ll try to answer any questions you might have. One other thing - we are fairly new to this. We’ve only had our tub for about one month so our experience with this is limited. We have a friend though who has been using hydrogen peroxide for quite some time and she also loves it. In fact, it was through our friend that we first found out about it.
And finally, I’ll also just add onto what Vinny said. There are two things you need to do with your hot tub water. One is the sanitizer, but you also need to make sure your water is balanced. It doesn’t matter which sanitizer you use, you still need to balance your water. It’s not that difficult, but as Vinny said it should be checked at least once per week.
