Water, SSKI

I know there are countless survival pages out there... wanted to here opinions from VWT. Distilling me own water, I stay 3 gallons up.. I know it would not "hurt" to add a drop SSKI to each gallon, for storage? drinking around a 1/2 gal a day unless I'm eating 1/3 of a seeded Watermelon daily : )

Still adding a pinch of citric acid ?
