Got a refractometer and WOW, way out...gotta fix

[Slick Fork]

Hi there,

Just got a new refractometer in the mail today and wow was my hydrometer ever out. My Hydrometer was telling me I was at 1.024 and the new refractometer says 1.030. 6 POINTS OUT!!! I expected to see a difference but that's huge.

So anyways, I wanted to bring my salinity back down to 1.024 and my plan is really simple. I don't want to do it all at once of course but I figure if I pull a couple of litres of SW out every day and top back up with fresh RO water that should be slow enough do you think? The system is a 100gal display with ~40 gallons in the sump.

Is my plan to aggresive, or to conservative? Should I maybe just do my adjusting during water changes? Let me know what you think.

Cheers
