When is it safe to use new saltwater! Tank just crashed

[josh11293]

I have a very established aquarium the unfortunately crashed while I was on vacation. I arrived home today and most of the coral look terrible. All the fish and inverter seem to be okay. I just mixed some new saltwater using aquavitro salinity salt. How long do I need to wait before I can safely use the new saltwater? Usually I wait 24 hours but this is an emergency

An hour or two of mixing is normally fine

How much are you changing?
Was it an outage?
What was the water temperature?
Can you test for ammonia?

It's a 20g I'll be changing around 5 gallons. It does appear to have been caused by a power outage. The water is back at around 79 now

If you have a small powerhead mixing it continuously, I would think an hour would be fine.

Hand stirring the recommendation is 6 hours, but if you are in an emergency situation, (fish getting lethargic, gasping, etc...) I would use it sooner.

Hour should be fine.

If thoroughly mixed, right temperature and salinity the water it should be fine to change the 5 now.

I would not disturb anything in this change to keep the stress down. Just siphon off the five gallons quietly and replace with the fresh mix.

If lucky was just a minor event that self corrects and you dodged a bullet.
