Hi, thanks for the feedback. The hot tub I've purchased comes with an ozone system (Arctic Ozone) and so my hope is that I can use Aquagarde with the ozone system, and do away with chlorine etc. Is that realistic or am I going to need to use chlorine at the same time as Aquagarde (or AquaFinesse for that matter)?
I think one of the main reasons for confusion is that it's not clear (at least to me) what the difference is between water that is referred to a "pure" (on Aquagarde's website they say "... gives you wonderfully pure and clean water, with no balancing, no testing, no smell and no worry.") and water that is "sanitized".
Thanks for any advice.
