Hey dcr,
I pretty much stink at remembering which test to use where. Maybe one of the old timers could compile a list of tests or point us to site which has a list of tests
You can get plastic laminating paper at your local office supply store that is really handy for laminating frequently used 'cheat sheets'. I take a few weeks experimenting with a process until I find out what works for me. Then I write up a cheat sheet and laminate it. Then you can take quick notes with a non-permanent marker right on top of the laminate as you further improve you process. The key point to remember for us newbies is take lots of pictures and notes to learn what works best and of course prep, prep, and more prep.
I am in the process or recharging all of my plating tanks with deionized water wich is pretty close to distilled water. I have found enough of an improvement that pure water is worth the costs.
