Note: The implication that test kits cost $30 is somewhat misleading. Many big box -hardware store test kits have extra fees associated with the kit [ $15-30 analysis fees, fees for faster processing ($10), have to be sent to the US with Customs declarations and extra shipping costs, etc.]. Read my DIY testing section for test kit limitations and an alternative DIY kit. Buyer beware.
