Calcium test - 0?

There have been some issues with the HTH kits from Walmart for hardness. I have one of these kits and have had problems with the HD test. I would think about treating the pool untill you have the results from Ben's kit.

The color when you add the indicator should either be pinkish (indicating hardness) or blueish (no hardness). Try adding more indicator drops. There are known issues with the test in this kit that have been discussed before in the forum.
