I am a new subscriber… Just discovered your valuable channel. I have several gallons of old discard film developing fluid. How do I get the silver out of it? Any suggestions?

Put a clean copper bar in the solution. The silver ion will trade places with the copper ions.

Will vinyl tubes do for bubbling the NO2?

Vinyl will probably break down after a couple of uses. P.T.F.E tubing would be the best tubing to use. Thank you for watching
