Ann,

Thanks...I was reading elsewhere that stopbath was essentially vinegar so why not. Now what about the developer. I would use something like Ethol UFG unless this is really toxic and there is anything that is not. Inquiring minds want to know .....or at least one mind.

I am considering developing my own B&W film. My film cameras are beckoning. Before I do this, I would like to understand how to dispose of the required chemicals. I would be using something like Ethol UFG on TMax or equivalents. It looks like fixer with a simple treatment (desilvering) is dumpable, but what about the developer and stopbath? I am on a septic system and don't want to spoil a good system.

Any suggestions either in disposal or alternative products is welcome.

Use White Vinegar - a teaspoon or two to a quart of water, for your stop bath. That was the first thing the guy told me when I bought my very first darkroom equip back in the mid 70's -
Better for you, better for the earth.
