How do I scale 1tsp per 30 gallons, down to 4 cups?

I think I may have some zoas with pox. I want to use Furan-2, but bought it in powder form, not in "packets." The package says one tsp per 30 gallons, but I don't want to treat the whole tank. I want to make a dip.

I need about 4 cups of dip. How can I measure this out? I have some of the little spoons from the salifert test kits that I could use to measure some out, but don't know how much they hold or how much I need.

C1V1 = C2V2.

You need 40uL of Furan-2. Just pinch in a few grains.

I wound up doing 15 little scoops, using the small red scoop from a salifert kit. It turned the water a little bit green. The Furan wanted to float on top and not mix in well at all.

15 little scoops into 4 cups? When the directions were 1 tsp in 30 gallons?
