Re: How do I use Bromine in my spa (or pool)?
350 gallon hot tub with new ozonator. tub recirculation and ozoneation is constant using small recirc pump. ozoneator is fairly high output. Had bad odor problem last year.
Seem to be fighting an odor problem.
I cleaned tub with chlorine-pumped out cleaning and flush water along with residue rv antifreeze, then filled it and added about two quarts liquid chlorine and circulated for a day. Cleaning included the cover interior with pool chlorine-looks good.
Dumped chlorine water and then refilled with new city water and put in a new filter.
Then added 2 oz of Sodium Bromide or mine, adjusted the ph using muratic acid and all was well. Heated to 104F. Put a floater in with one tablet. Looks like dissolving about 1 tab weekly. Got the TA to about 80. Then a day or two later, tub has an odor so I added a cup of pool chlorine. Maybe a little more than needed? Now got a strong chlorine odor along with a musty smell. Bromine test was off chart strip and ph went high. Turned on air blower for about two hours to help with ph and try to lower br/ch levels. Ph was then too low so added some ph plus for pools and got it in range. Aerated more with blower and ch/br came to a little under 9. Still having various odor problems. ph went low so adjust with muratic to 7.4 or so. Fill was about 5 days ago and used tub three times, one person. Presently have slight musty odor but bromine/chorine now tests low?????? In one day it went from 10ppm ch/br to near 0.
Last year used nonchlorine shock and thought the order might be coming from the sulfur based additive-is that possible?
Question
1. What br level to shoot for with ozone? What ch level to shoot for with ozone if I decide to change due to odor.
2. Can i use test strips to measure low br levels???
3. The odor I get is a foul, musty odor. Last year, my swim trunks had a permanent odor. Any idea what I am doing wrong? I thought that the bromine system had less odor but I am finding an odor.
4. Tub manufacturer suggests since tub has ozone that you float one tablet of Br per week, sanitize with PSul weekly.
5. What am i doing wrong.
Had a number of pools and can't believe this little hot tub is giving me such problems?????????
