Anna,
I will give the FC overnight test a try.

As for the metals, I've not done any testing this year, but I can ask the pool store to run that test for me. My fill water is from a municipal water source that is always rated (by whomever those people are that rate water) as one of the purist in the nation. Also, I've never put any Cu base algaecide in and have only use poly quat as needed. I did use the Frog mineral system for the first 3 years, but am not using it this year because I kept having problems with cloudy water by mid last year so I wanted to adjust my routine (and save $100 by not purchasing a mineral pack).

Thanks. I will give those a try.
Andy
