It is copper, and yes we did overdose with algaecide before I started reading this forum, won't do that again. But I also have iron which I think is from topping it off with our tap water which is public water however it is very hard.
The water is looking brownish green, and cloudy, we can only see about 1-2 ft. down. I do have a blue liner.
I was going to get some sequesterant today and add it just in case that was part of the problem. I did not know it wasn't a good idea to shock with cooper in the water until late last night. Although I'm still not sure why, is it because it will causing staining?
Yes, I am using a drop kit for the cl and ph, I don't know how to test for CC.
I will start adding another gallon of bleach today to try and get the CL up to 15ppm.
Thanks, I will post again once I have added the sequesterant. How long will it take to notice a difference in the water if the metals are causing the green/brown water?
