Using old salt water

[BlueWorldJeff]

I was making a batch of Instant Ocean two weeks ago when I ran out of salt and only got the SG to 1.022. I didnt use it at the time for my water change and its been sitting in a rubbermaid trash can for two weeks in my garage with a lid on and no circulation.

I got salt now and am going to do a change today. can I add to that mix or should I toss it and start over?

You can test for Ammonia, Nitrite, and Nitrate to be sure, but it should be fine.

Just add the new salt and it will be fine. :)

I used the water and added about another 20 gallons. We shall see. Thank you for your help
