how long do we need to wait for

[Jakuson]

I am wondering what is the minimum amount of time needed to wait to be able to use the premixed saltwater for water changes? Anyone knows?

Few minutes enough if you have stir it vigorously.

depends on how sensitive your livestock is. Most fish generally can deal with freshly mixed water. But more sensitive corals should not be exposed to undissolved salt as the particles will sting them. If possible, you should mix your water and then leave it to stand for a few hours or a day with a small wavemaker or something that can create water movement.
