thinning heavy syrup

[psparr]

I have 5 gallons of syrup that I made approx. 1 brix too heavy. Is there a formula for how much distilled water or permeate to add to what I have to bring things back to normal?

There is, I’m sure someone will chime in so don’t quote me on this, but I think it is 1/2c per brix per gallon.
