diluting High salinity with RO water question

[joshuashih1]

I was mixing salt water and made 2 gallons of salt water with a base of RO water. My refractometer is reading 1.03 PPM and I want to mix in fresh RO water. I desire to achieve 1.025 PPM. About how much RO water should I add per gallon of saltwater at this salinity to get as close to my desired salinity?

Kinda helps. when its asking for ppm and I put 30 am I acutely putting 1.03?

You can change the units to SG.

1.03 Specific Gravity not ppm
