Thanks for the advise!! I added the sequesterant yesterday. The water looks better, first improvment that I have seen for weeks. However it is still green. I can see apx 2-3 ft. down. I will be testing the water later today and see if there is still any metals in the water and if so adding more sequesterant, is it ok to add two days in a row? If I do not have any metals left then I will continue to shock to a level of 15ppm. I will post the pools number later today. Thanks!!
