I was just thinking about finding a hot tub forum. we just got a softtub portable tub, 6 person with an ozone generator. We are trying to figure out how to best go about sanitizing it. We bought a whole bunch of chemicals from the pool store but they seemed to have forgotten to sell us bromine. They gave us this all in one shock that has PH stuff/alk stuff/ cal stuff, he said to just use that once a week. Well I tested the water and it has almost 0 chlorine/bromine and 8.0 pH. So I went out and bought a bromine floater and tablets and let it swim in there for day. The readings are still barely .5 bromine, is there a better way to get the bromine levels up faster. I put about 6 tablets in and set the floater on max dispersion. The PH also seems to want to go high, is it becuase I put about 4 capfuls of that all in one shock in? and am I suppose to test the hot tub water at the pool store and balance it just like the pool? Ph/alk/cal etc etc etc.
