Premixed Saltwater?

[droth]

I wanted to ask about mixing your saltwater. Presently I’m cleaning and changing about 25% of my water on a weekly basis. Changing water weekly means mixing a lot of saltwater and I want to be able to make it and store it.

Can I make up saltwater and store it in 18 litre jugs.

How many weeks or months can I store this premixed water for?

From what I have read about this subject about 2 months, I would keep it in a cool dark place, and make sure your jugs are cleaned before hand so you do not have a chance of a bacteria in them before adding the salt water.
