I've had some staining in the pool since I opened it up this spring. It wasn't there last fall. I've tried a few things at the guidance of the local pool store but nothing as solved the problem. I've tried a Scale and Stain Remover that didn't work. I tried black algae remover that didn't work. I've tried SLAM thinking maybe it was organic with no luck. I tried rubbing some citrus fruit on it to see if that had any success in removing and it didn't but haven't tried the Vitamin C tablets. Just hoping maybe it's an obvious issue that I'm missing.



All my readings are normal otherwise, Copper has come back slightly increased at times but nothing crazy. I fill my pool with well water every spring and to maintain level. Any help would be appreciated.
