+1. I may play a little fast and loose with my salinity, but sometimes if I haven't done a water change in a while and I've been really wet skimming, my salinity can drop to 1.023. My solution: dump an entire cup of salt directly in to the largest chamber of my sump, let it dissolve, test salinity, and if it's not where I want it, dump in a cup more.

Keep in mind that the total volume is 375 gallons so in a smaller volume of water I'd put in a smaller initial amount of salt, but if you add it to your sump far-ish from your return pump, I doubt you'll have problems.
