Well, here is my dilemma:
I did a Jack's Magic copper stain treatment. It has been 4 weeks. According to the instructions, you will get false FC readings for 3-4 weeks. I am still getting the readings.
Now, for several months, I have had some green in and around the pool, including ON TOP of my solar cover. I have attributed it to dry weather and pollen, as my CC has always been 0. I have only been getting the CC since the treatment.
The green "pollen" is still around, and may even be getting worse. So, now I am unsure if I am having an algae breakout, or I am still getting false reading. Currently, my CC is about 8, and I am afraid to add too much chlorine to battle algae should that be what the green is or is becoming.
My water is crystal clear. I could tell heads or tails on a dime in the deep end. But, the green is sticking to the sides in some spots. It comes off easy, brushing and vacuuming up with no problem.
