1. Done: added both polquat and CL (chloringting granulars)
2. The CL I'm using is labled as 68% Calcium Hypochlorine and 32% other ingredients as provided by "Poolife". I called Arch Chemicals, the company who produces the product, and had them pull the MSDS sheet. They confirmed that there is no copper in this product.
3. Just to be clear: do you mean I should take store bought "bottled water" or should I be bringing them tap water in a bottle as the second water test / along with my pool water.

Thanks,
