What is used water good for?

[dherman15]

I was wondering if anyone found a use for the water they syphon out during water changes?
Currently I just throw it in the bushes but was thinking this may have some benefit that I don't know about.

thanks in advance

Mine goes down the drain.

With the salt in there, I don't feed my plants with it. Used to with fresh.
My used Tank water comes out and goes into the live rock bin as its water change.

Not much good use for saltwater! Throw it on areas you don’t want grass to grow?

You'll kill the bushes unless they're salt tolerant, or it is a very small volume.
I use to condition rocks as lost in the sauce said.
Rest down the drain.

Rinse sponge and rock with it. Use 2 gals to start a pico. Lol.
Soak bio pellets.
Not a lot.
