I have a bottle of 6% Oxalic acid with 30% sugar.
I thought the dilution rate should be 3%?
Should I cut this by half with water?

You need 50-60% sugar content too.
For 10 hives you need 300 g sugar + 300 g water + oxalic acid 22 g = 4,8 dl
******************************
You have now liquid
.... sugar.... water
6 % .... 30 .... 70 = 100 g
To get double volume you need 100 g more sugar and water, but in opposite rate, and you get 50-50
you add sugar
70 and water 30 g, so you have both 100 g +100 g = 1,6 dl. = 50% sugar = for 3-5 hives.
If you make 3 doses, you get for 10 hives
Original juice 300 g (90 sugar + 210 water)
sugar ..........210 g
water...........90 g
________________
..................600 g = 0,48 litre
It is better to confirm my calculations
