I'm putting in a system in a new house.

I'm planning on using National Testing Labs: ntllabs.com (unless someone has a very strong recomendation for someone else)

I'm looking for a recommendation on which of these tests I should use.

I'm not adverse to extra data but I don't really need to pay extra for something that has no value at all to me.

This is city water drawn from wells. It is chlorinated and I know it has at least a moderate amount of hardness.

Thanks!
