Eventually you should find the amount you need to mix in to get to your specific gravity per gallon amount.
Try to be precise as possible
Good luck on the SW

+1. The only advice missing here is check the salinity of the 90 gallon first. Evaporation leaves the salt behind. You'll find in the salt world that your salinity is usually high in which case you add ro
water to achieve 1.025. Good luck with the move
