mrwrick Posted November 8, 2018 Report Share Posted November 8, 2018 I use bromine in my Hot Springs Classic spa and run a Del MCD-50 Ozone generator 24/7 with my recirculation pump. My Taylor test kit shows consistently high pH, 8 plus. TA is also over 100. I attribute this to the high amount of ozone in the water due to the 24/7 operation of the generator. How much borate buffering should I add to reduce my pH? My spa volume is approx. 350 gallons. How should I add it? Measured amounts over periods of time, as with bicarb of soda to elevate TA? How long should i wait to take an accurate reading of the net effect on the water balance? Thanks to all in the Forum for great advice.
