I know that when making new saltwater it should aerate for 12-24 hours. I made about 3 gallons of saltwater last night and just let it sit in the bucket (with no lid, nor any method of aerating) overnight. Would this be harmful saltwater to use now?? I added it to my QT, which already had about 7 gallons of saltwater from my main tank in it. Is the water in my QT now unsafe?! (There aren't any fish in my QT yet).
