Maybe you can I don’t know? But why would you. Any chance you get to change a little water should in my opinion be used to change water in the main fish tank.
Using water to do two or three jobs before you toss it is standard practice in my house.
Using clean water just once to wash media ? Are you mad?
Don’t be frightened to change water in a fish tank.
Please don’t take offence at my questioning your sanity, but if you paid as much for every litre of water as I do you would find multiple ways to use every litre/ gallon.
