really confused by dosing kH math

[dandoozled]

I am slightly confused and am trying to piece everything together but don't want to mess up. So my reef tank is at 7.5kH and I want to increase it to around 8.5-9kH, I am using reef builder alkalinity booster, the instructions say to use 3g or 1/2 teaspoon per 40 gallons which raises the kH by 0.7, I have a 13.5 gallon tank, and in total I'd say there is about 10 gallons of water.. how much do I dose?

I simply used the reef calculator HERE, using 10 gallons, 7.5 to 8.5 dKh and came up with half a tsp of Seachem Reef Builder (powder). Hope this helps.
