Are there any uses for old saltwater

[TOM BLEVINS]

Dry it out, then use the sea salt for cooking?

or in your bath like epson salt? HA:bounce2:

I haven't checked this thread for quite some time, so forgive me if I missed it but:

I have been using water change water to culture phyto and rotifers. I dilute it to 1.019 salinity, and microwave 2 liters for 10 minutes to sterilize it. I have been doing this for a couple months without issues. if anyone knows why this is playing with fire, please let me know!

I use mine to kill the weeds in between cracks in the concrete in our backyard.

Always knew saltwater was great for killing grass, never to kill weeds (too lazy to try it out) Thanks for the info, now I will never have to use that nasty round up.
