I am much happier using chlorine ( bleach or di chlor ) than the bromine method. Everyone in the family says the water is less harsh and no odors. And we have much less foaming and the water is crystal clear. But you have to add a little chlorine EVERY day. Chlorine is less stable at the higher temps. Add the chlorine right after you use the tub, not before. You will find that the next day, it will be gone,but that is OK. If the tub is covered, it should remain relatively sanitized until your next dose that day.

One thing, it is always more work to keep the alkalinity ( and thus pH) adjusted in a hot tub because of the aeration. I check the alkalinity regularly and add baking soda as needed. then you can adjust the pH as needed, but not before adjusting the alk. I tend to run my alk ( and pH) a little high so that it stays in the normal range longer.
