The only time you need to use something like Metal Free is when you have metals (typically iron) in the water. And even then I don't recommend using that specific product. There are a number of superior sequestrants available.

Many pool store, but not all, can test for metals. There usually isn't any point in bothering to test for metals unless you filled the pool from a well or have some specific reason to suspect that there are metals in the water. Municipal water hardly ever has enough metals to have any effect.
