    calcium ring at water line

    I am wondering what the best way is to clean off the little bit of calcium ring that builds up at the water line on the vinyl liner. I'm using the BBB methods and I don't want to use anything too harsh. Thanks.

    If you are sure it is calcium, then some diluted muriatic acid, four to six parts water to one part acid, should clean it up. Water test numbers would help us advise you how to reduce the chances of the same problem happening again.
