Welcome to our forum.
Okay. That's sounds reasonable. I was looking I to the Clearwater blue product line but it's seems a little pricy
I have a tub since 4 weeks, so not yet an experienced user.I use the sundance sunpurity (ie the same as zodiac nature2) system and i think it is great untill now.It is a miniral cartridge which you use in combination with MPS (like Leisure Time renew). Chlorine you use only at the start and as needed when the water looks like it needs it.We soak every day, and i still haven't used any chlorine and the water looks crystal clear and feels perfect, no dry skin/red eyes afterwards.Our hottub supllier was not aware of this system because for some reason here in Europe it isn't sold but he was also amazed when he saw our water quality during his visit yesterday.I only put MPS in the water after soaking, and that's it. So, very happy with the system!I found out that it is really very important to keep the PH in good values, and the only way to do that is with a digital PH meter.goodluck
Like Tman says how the water looks does not tell you about dangers of bacteria. This is one of the big dangers of so called alternative sanitizers, they may kill algae (or prevent it from growing) which you can see, but do nothing to prevent the growth of dangerous bacteria which is much more difficult to detect. When using Chlroine or Bromine, lack of algae is a good visual indicator that you have enough sanitizer in the water to also kill the hard to see bacteria.

I guess then it should be safe? (in contrast with all the alternative sanitizers on the market).
