How long should you ideally leave your new water mix before adding it to the tank? The other forums range from 5 minutes to 4 days.

I just wait until it's totally clear/mixed, check the salinity and then use it.

Leaving it to sit before using it, is all about letting pH stabilise. You should ideally aerate it, which will not only add oxygen, but stabilise CO2 levels, which has a big impact on pH levels. If you're using a pump to mix it, make sure the surface is being disturbed.

That said, if it's an emergency, then the pH swing is most likely relatively small (will depend on salt brand), so I'd stick it straight in if need be.

Red sea Pro (black bucket) say that it should be no longer than 4 hours............don't know why though.
