Can anyone interpret this for me?

What you've found is basically a generic version of Oxi-Clean:

Sodium Chloride is salt
Sodium Carbonate is soda ash or pH Up
Sodium Percarbonate is the active ingredient in Oxi-Clean

It's sodium percarbonate, an oxygen bleach. One company once sold it for non chlorine shock for commercial pools but no longer does because it was not suitable and created more problems then it solved.. The only company that I know of that is selling sodium percarbonate now for pool use is Proteam which sells it as System Support, a speciality product for quickly clearing very badly fouled pools. (It work, btw, but it's expensive and requires a lot of dry acid be added at the same time to keep the pH from skyrocketing.)
It is NOT chlorine and is not suitable for santizing a pool.

Sodium Percarbonate is most well known as the laundry additive, Oxyclean.

It can be a useful product for converting a biguanide pool (Baqua, SoftSwim, etc.) to chlorine in the initial stages of the conversion.

Don't even think about using it!
Sodium Chloride is your regular table salt.
Sodium perchlorate releases hydrogen peroxide as the oxidizing agent. There's no "active chlorine" species thereneeded for your pool.
Sodium carbonate is washing soda and will increase your pH.
So why is it called "dry bleach"? Because the released hydrogen peroxice does the job of "bleaching", but you don't want that kind of "bleaching".

One more thought about the 55 gallon drum. It's going to weigh about 400lbs.
