We have been successfully maintaining our pool through out this summer using using liquid chlorine at 10% and muriatic acid. I have Taylor test kit and use it faithfully. I was talking a friend that is in the pool maintenance business and told be that adding liquid chlorine adds salt to the water and can cause salt levels to be too high which can be corrosive. He is recommending a Taylor Test kit K1766. I do not have a SWG.
My question is do I really need to be concerned about this?
