If I understand this right Cl ion is not subject to to degradation by UV radiation when attached to a CYA but yet it still remains as FC because its a weak bond. Cl ions are always looking for nitrogen to bond to so when not bonded to CYA on its bonds to a N and comes across a bad guy it attacks for lack of a better term and becomes a chloramine or breaks itself down. So knowing I want my FC at the high end due to all the stuff that will get into the pool and the kids me and the wife, 2 dogs etc, I want to run my FC at 7, from research it appears that 10ppm CYA protects 1.5ppm of FC so my optimum CYA would be 46.6 to protect my FC and not waste FC. I know levels will fluctuate so lets call it 50 ppm CYA which is close to what is recommend on the pool-school/recommended_levels chart. Now my pool will have lots of aeration(kids) direct sunlight from on average 9:00 am to 6:00pm, and lots of leaves bugs etc. So I expect FC usage to be higher than average, scratch that with this pool I already know it is. So it got me into this somehow...
But according to http://www.iwaponline.com/jwh/006/0513/0060513.pdf
If I wrapped my brain around this, I would want no more than about 30ppm of CYA to get maximum effective inactivation of cryptosporidium. I think....
So A maybe someone could explain a little better how hypochlorous acid actually kills bacteria, maybe why the ions attach to CYA, and how does superchlorination remove chloramines from the water, simple outgassing of the ammonia? Goes back to reading A New Kind Of Science, much simpler... than taking care of a pool...
after this ive been reading up on bromochloramine oxidation of N,N-diethyl-p-phenylenediamine(DPD) in the presence of monochloramines
