Info from Clorox on using their bleach for pools

[waterbear]

I checked these amounts in mwsmith2's bleachcalc and got about 2 ppm (for example 1 quart or .25 gallons in 6000 gal water gave 2.2 ppm, 6 cups or .375 gal in 10000 gal water gave 2 ppm, and 1 oz per 100 gallons gave 2.1 ppm ) when using 5.25% which is the listed concentration on regular (not ultra) Clorox. It seems they are recommending a 2 ppm concentration based on their dosage which is in line with the newest minimum recommended dosing of many state Health departments and in line with Ben's best guess table for non stabilized pools. "Clorox Bleach-Regular Scent" is the name they give to their unscented bleach products (and they do state on their website that this is their only EPA registered bleach for sanitizing and disinfecting:

so this would be their 'unscented' bleach.
I agree that their recommdations for stabilized pools are not good nor are their recommendation for maintaining a .6 to 1 ppm residual.
It does seem that the 5.25% for their regular bleach as listed on the label is correct for our purposes based on bleachcalc and I would a s s u m e the 6% ultra bleach is also correct since that is the listed amount on the label of that product.
It is interesting that the MSDS for the regular bleach lists the concetration at 6.15% and the ultra bleach and the commercial Ultra germicadal bleach lists a range from 6% to 7.35%. Perhaps the higher concentrations are to compensate for loss of strength on shipping and storage so the consumer will have a product with at least 5.25% for the regular and 6% for the ultra products?
Hope this info is useful.
