What Is Total Hardness of Waterの概要と注目ポイントを徹底的にカバーしました。

In plain English, total hardness is the measure of dissolved calcium and magnesium in your water. Think of it as water that has been on a mineral-collecting road trip, picking up souvenir rocks from the ground. It’s not dangerous—it’s actually healthy to drink—but it can be a total nuisance in your pipes, your laundry, and your morning shower. The harder the water, the more those minerals are just hanging out, waiting to cause trouble.
