I purchased 5 Gallons of salt water to do a water change with, then had to leave town before I had a chance to do the water change. When I get back it will have been a week. The water has sat in my garage in a sealed container. Is it usable still? Should I bother testing it first? Should I test for anything besides NH3, N02, NO3 or ph?
Is there a limit to how long you can store salt water mix?
