Hey BMR,
2 cups of salt is not enough salt... did you mean 2 kgs? For my Yukon the minimun is 3.3kgs of salt, roughly half the bucket that is provided. The water will be cloudly after the salt is added initially and then it clears up in a day or two after filtration. The cloudiness you are mentioning sounds like it's just after you run the jets with the air on which like you said clears up after it settles a bit.
When you add Refresh you will get a small bromine reading if you test shortly afterwards. I personally had a small reading of bromine once but my Onzen wasn't working at that time so the reading came from the Refresh. My issue was that the electrical wires to the Onzen system were never hooked up.
I'm also curios about the smell, I think I've read that when you open the tub that you will get a whiff of ozone. The Onzen system is a 2 part system from my understanding, 1 piece of it is a ozone generating system and the other is a bromine generating system. I've also heard though that if you do have a chemical smell that you haven't added enough Refresh to counter act the byproducts of the bad things killed off from the bromine. Can anyone clarify that Onzen systems should have a chemical smell and if they do what should be done to fix it?
I'm no expert, I've had my tub since October 08 but my best guess is that you still have a lot more salt to add, at your current salt levels no bromine will be generated by your Onzen system.
