I'm just opening my Minnesota pool for the 2024 year. Tested the water yesterday when we first turned the pump on, and the FC was zero, as anticipated. Pool Math recommended I add 1.7 jugs of 12.5% chlorine to raise the FC to 4, so I did that a few hours ago. Just went out to measure and the FC is measuring above 20.
I'm not worried; the water is cloudy after adding the chlorine, but I know that's part of my process. But I am curious why the levels are so much higher than Pool Math said to expect. (The SWG cell is off still, by the way. Waiting for the heater to get my water up to a warmer level.) Any chemists want to take a stab?
