Last season we battled metal staining in our pool. This year it’s the same thing. Vitamin C works to lift the stain and then I add sequestrant but a week later the staining starts to reoccur. I know we have high levels of phosphates from adding multiple bottles of sequestrants. The pool store says metal levels are not high, but what else would cause the yellow staining and be lifted with vitamin C? I don’t know what to do to avoid constant vitamin c treatment and sequestrants. Please help!
