strips are at Walmart. About ten bucks, and I too have to go to parents for water. And it shows differences in water from just 100 feet away. My home water comes up full of nitate and nitrite. Thief water if purer than the fresh fallen snow. Hardness comes from metals, alkalinity comes from natural salts in water. If u do have to use water conditioner make sure it doesn't say slime coat. water filters don't remove nitrates, only reverse osmosis. And conditioner doesn't remove it ithor. So that's most important.
