VERY IMPORTANT!!!!!!! DO NOT TRY AND TEST OR AJUST YOUR pH WHEN THE CHLORINE LEVELS ARE ABOVE ABOUT 10 PPM. YOU WILL GET INTERFERANCE AND A FALSE HIGH pH READING. From two of your posts above:
CL 14-15
PH 8.0
and
CL 6.0
PH 7.8

Sorry for shouting like that! Here are my thoughts, I could be wrong.
The green color does look like copper, even with the sequesterant you might be oxidizing the copper with the high clorine levels. I think the stuff in the pool is dead algae now and the filter is not taking it out for some reason. What kind of filter do you have? You might want to make sure it is working properly. Is the pressure reading normal? If it is a sand filter you might have channeling in it. You can clean the sand if that is the case. If it is a sand filter you can also add a bit of DE to it (enought to raise the pressure 1psi) This can help it filter out the finer stuff. Try letting the chlorine drop to normal levels and hit it with a seqesterant again. Jack's Magic Blue Stuff is designed specifically for copper. You might want to try that and see if it clears the green. Get your chlorine and pH levels to where the bottle says before treating. If it works THEN lower your TA!
