What is your salinity if it is high a ro-di top off would be fine.. I don't mix my own salt water so I'm not sure on the specs on that part.. But I believe your sopost to wait 24 hours after mixing..

I make my new salt water up just before using it. As long as the pH, salinity and temperature are close its fine to use right away. There is a long discussion here on TRT about waiting 24 hours but the data collected was inconclusive and did not prove out the 24 hour theory that the pH is unstable.
I've been keeping saltwater for over 30 years and reefs only for about 25 and never had a problem when mixing my water shortly before using it as long as I adjust the temp, pH and salinity to closely approximate the display.

Is there a problem running your system 1 quart low for an additional 12 hrs (till in the morning) while it mixes?

If it is strictly the level of the water, I have heard of others displacing the water by placing a sealed clean jug of water in the tank to actually raise the water level.

Zombies will break into your house and eat you. Don't believe me...? It's your brain man, whatever. Watch a movie or read a comic book - this stuff happens.

When salt and water mixes, there are a LOT of chemical reactions taking place. Take a bit of your marine salt and put it on a plate or a shallow dish. poor a bit of water in and feel the mixture - it gets pretty hot. It's my guess that the manufacturers put this warning on the label so some MUHron doesn't pour a slurry of wet salt-mix into the tank, fry their fish, then sue the manufacturer for not being fully informed.

However, there's a thread where this debate took place. After a few pages of "[checked the water an hour later and the parameters are still the same]," it was unofficially concluded that after a couple hours, there is no significant change to the water parameters that would be cause to NOT put it in.
