Confused about K-Meta dosage

[HappyWino]

I seem to be getting conflicting information about how much k-meta to use to sanitize a must and was hoping somebody with a little more experience could straighten it out for me

Pretty much every recipe I have come across suggests 1/4 teaspoon for 5-6 gallons.

The instructions on my packet say "Add 1/4oz (less that 1 tsp) in 10 gals to obtain 75 ppm of SO2"

My scales say that 1 level teaspoon is just barely under 1/4oz.

I don't have an SO2 test kit so I can't just throw all the conflicting information away and do it the right way...and advice?

Cheers

Well, I'd use 1/2 teaspoon in 10 gallons, which would be more like 50 ppm, or 1/4 teaspoon in 5 gallons.

You can work it out yourself if you convert your measurements to litres and grams. Remember that only half the k-meta is so2.

1 gram in 10 litres gives 50ppm.
