lowering salinity safety

[Pete polyp]

I just calibrated my refractometer and the sg is 1.028. According to an online salinity calculator it will take 7 gallons of rodi in my 65 gallon system to change it to 1.025. Should I change out 1 gallon per day for 7 days or should I move faster?

The 7 day plan sounds good to me. There is certainly no hurry.

I should probably dose some two part in with that huh? Like 2ml of part 1 into to the system and 2 ml part 2 in the rodi?

You mean because the lowering salinity will drop them? Yes, you can dose to offset that.
