Pool still green

See i f you can find a different pool store that tests for metals. I would really like to know if there is copper or iron in your water.

OK gang, I got to a "better" pool store yesterday that confirmed my numbers (I guess I do have the aptitude for testing ). Evidently a TH of zero is a problem! Solution: 40 lbs of calcium chloride. This morning my pool is a crystal clear blue!
