Hi, Lee,

You have obviously thought long and hard about your process. I would interject that, once you start, test and post your numbers here on the forum daily. That gives everyone a definitive point to start and will result in the best advice from the forum along the way.

I am assuming you cannot drain and refill. That would certainly be the most bulletproof way of getting your metal out. Do you have an idea as to how it got there? If you refill from the same source, you will eventually have to do this battle again.

P.S. I, and others on this forum, are not big polyquat advocates. I've only used CL and have been successful to this point. I think I understand why you're using it but Ben seems to think it works much better as a preventative than a cure.....Pricey, too
