I think you are asking how much bleach is equivalent in Free Chlorine (FC) amount to 10 ounces of 67% Trichlor, correct? The answer is 95 fluid ounces of 6% bleach or 69 fluid ounces of 8.25% bleach. The newer Clorox bleach is now 8.25% while the older one and some off-brands are still at 6%. Instead of figuring how much bleach is like a certain amount of Trichlor, you should instead use a test kit to figure out your current FC level and then based on the FC that you want, use The Pool Calculator to calculate dosing based on your pool water volume.
