Looking to find out how much FC one bag of 68% cal-hypo adds to the water.
I know the ammont 6% bleach adds but i have been trying to find out how much cal-hypo adds. I have not been able to find it on the bags or even searching the forums.

68% bags say one bag per 10k gallons , but theres no way of knowing how high your bringing up your FC unless you check often during adding the cal-hypo.
Id like to know so i can bring the water to shock level based on my cya.

Is there a ball park figure per 10k gallons for the most common 68 and 73 % cal-hypo one pound bags of shock.
thanks
