I want to remove 0.5 ppm of CC. The formula, CC x 10 = ppm of FC to add to reach breakpoint, is clear enough. However, because of the presence of 75 ppm of CYA in a 20K, SWG, IG pool, should more than CC x 10 = ppm of FC be added to overcome the CYA? And, if so, should that additional FC be 40% of the CYA?
I am going to be using 12.5% sodium hypochlorite.
Thanks
