Is this the correct RV Antifreeze for ballast

I contacted the local farm supply place about drums. He said he can get drums, but he also offered a case price of gallons that came out to $1.97 per jug. So that is not much more than the WWF. And has the advantage of corrosion protection additives along with less environmental risks... I'm going that route.

Thats a pretty good price..
