Until Marie (our metals expert) gets a look at your post, I would suggest that you go and read some of the other threads in this section. You will learn a lot from hearing what she has told some of the others to do. She'll be along shortly to help, although by then, you may have read enough that you can go ahead on your own. Also read the stickies at the top of the forum. I would also suggest that you go buy the $15 (or thereabouts) 5 or 6-Way test kit at Walmart that is a drops-based kit and use that instead of test strips. You'll get more accurate results. Good luck.
