There is a cloudiness in our pool water that I can't seem to get rid of. All the test #'s with my TF-100 kit are basically good. With all the rain in the last 6 weeks, we have had several thousand gallons of ground runoff enter the pool. It's a light yellow/green/brown cloudiness (hard to tell the exact color.) Last year the opening went smooth and the water was crystal clear a few days after opening. This is only our second year with the pool. I noticed a couple of bottles of Metal Control lying around from the previous owner. Maybe they knew something we didn't! I've been shocking the pool for the past 2 weeks, waiting for the liner to settle. Maybe metals entered via the ground water, and is the cause of the cloudiness. Is there a way to test for metals. My TF-100 kit doesn't have that test. Thanks in advance.
