We really don't recommend any brand except Clorox. The others are not certified for health use. . . because they aren't made to the standard of the Clorox brand. The concentrations can vary by quite a bit from the 7% Sodium Hypoclorite the Clorox is sold at. It's better to use a known starting concentration than take chances with an off brand. Even Clorox increased their concentration a few years ago without warning. That's why the update to 24 capfuls to account for that change in concentration. 

Thanks! I will nail down the particulars. What type of Clorox is best? You said the germicidal kind?

Yes. It's straight Sodium HypoChlorite and water in solution which you will dilute even more, no laundry additives.
