Does it matter what container to use for testing?

Randy,

I had an accident with my plastic vials used for testing salifert. I do have extra glass ones though from when i used red sea. Does it matter what container we mix the solutions in as I'm guessing it'll show color change either way?

It shouldn't matter, just soak the glass vials in vinegar for a few to clean out any residue.

I agree it won't matter as long as the residue from a previous test isn't in it.
