Finally opening today, and of course I have some discolored water. Lack of chlorine+warmer temps=green water. I get it. It's not the first time. And my water level is down. Down enough that I have to add some before the pump will begin circulating. In the past, adding water -- even my supposedly "soft" water from the house -- has caused discoloration due to iron and other metals. I have dealt with this in the past with Metal Magic or similar additives. But ... they always say avoid high levels of chlorine, which I need to clean up my water! As I add water and start the pump, what do I do first, chlorinate or treat the water for the metals I know are lurking out there? (BTW, I have no tests yet of the water. The color tells me it needs chlorine. Fast!)
