How long do you age your new water?

I have a SW tank and a FW tank so I have a 40 gal garbage can of each heated to 79F with a bubble stone running. After a water change I refill the SW can with the FW and mix the salt with a submersible pump. Then refill the FW can with RO/DI water. Works for me

Ditto, I also keep mine aerated to raise the ph.

Does it count if I mix the water and then age it until I'm ready to get off my lazy bum to do the water change?

:P

Use RO/DI water.
As soon as salt dissolves no heat no air. Changing 5% per week.
Been doing that for 9 years now. Emptying the bucket strait into the tank.
All is OK on all tanks.

I voted for 24 hours because that is the minimum I usually leave it however if I had the room I would always keep salt water mixed up and ready to use.

This is interesting and kind of goes back to a post I made a little while ago - I leave it with PH's, heater and salt for weeks at a time. So far it's served me well, and ensures if there's an emergency, I can dip right in and have premade goodness ready to rock. I've left it up to about a month and a bit when things go a little insane, and so far no issues as long as the temp and salinity match
