Re: Bartier Disinfection Index
DOH!!! I'd just cleared up a mustard algae problem by bringing my pH way down to 7.8 (oh yea, i'd let it creep up a bit...) This index makes it obvious why that worked and why the SWG people seem to have fewer problems with algae etc. The pH of pure saltwater is 7.0. The SWG manufacturers tell the owners to add HCL (muriatic acid) to keep the pH below 7.6 or even 7.4. Thus their pools are much more disinfected. I'll have to find a cheaper source of HCL. That should be easy here in Texas' Chemical Coast. ;-) Those trichlor pucks with their very low pH are looking a whole lot better as well!! Thanks and Aloha!
22,000 gal gunite pool, 1.5 hp pump, DE filter, and dreams of a SWG.
