5 gallons of saltwater how long to mix?

[serbusfish]

I have added some unexpected additions today and have no saltwater to hand, if I wanted to make 5 gallons how long should I mix it for?

If you have the time I would let it mix for 24 hours. If it's an emergency just make sure it's the same gravity and temp as your tank. Just my opinion, you will find a lot of varying opinions on that question.

For water changes I only ever mix for 12 hours for water changes, in 8 months of reefing this has always been fine

I was just wondering as it was a smaller batch of water could I mix for perhaps an hour or so, I manually top off with RO and my tank has a water level line, as the water has now dropped due to acclimating the new arrivals I dont know how much water I need to top off to.

I do overnight... 8 - 12 hours.

In a pinch, mix it until dissolved and use it. In a perfect world, 12-24 hours

What kind of salt is is?
There are some brands that you are not supposed to mix for more than 4 hours, and some where longer is ok. Idk if any of the regular ones that are sold in stores nowadays actually recommend mixing for a really long time, but it would be easy enough to find out.

Same, salt goes in around midnight, then between 12pm - 2pm the next day I do the change.

Cheers, i'll mix for as long as I can and check salinity/KH etc before using.

I've used to reef crystals after 1hour of mixing

If all else fails get a hand mixer from the kitchen and go at it until perfectly clear. The problem is in undissolved trace elements and buffer.
