Saltwater dilution ratio?

[TCoach]

Ok, was able to visit the reef I’m adopting on Saturday and check its salonity with my Hannah probe. It was measuring 31ppt. Does anyone know the ratio of how much r/o water to add to bring down 1ppt per gallon?

Currently I have ~60 gallons mixed up @35ppt and really don’t want to dump it.

Thanks!

Hydrored already answered the question, but out of curiosity, why 1ppt? :3

I didn't know about the calculator and was preparing to do a bunch of math. 1 ppt decrease for a gallon would have made the math easier.
