Uses for old saltwater?

Hey guys first timer here ️
Just curious is there any uses for old water after water changes? I live inland of Australia and water saving is high in my town, I recycle my rodi waste water into plants and things around the house, but curious is there any use for old saltwater?

I don't think there is any use.

Some people find it useful as a weed killer in driveways and walkways, etc.

I'm thinking about mixing in vinegar ( and dish soap) and spraying it on some invasive ivy and blackberry I have growing out behind my shop

It KIND of works. Typical saltwater weed killer is highly concentrated, but adding vinegar might help!

Yeah the salt mix is weak. I think the normal mix would be 1 cup of salt to 1 gallon of vinegar, with a dash of soap.
