Since we're new tub owners, one of my questions is how often do you add water to your tub? The obvious answer is: "as needed", but I add water at least every two weeks, sometimes once a week, depending on how much the kids splished and splashed in the dang thing
So, after I add water I usually do the weekly shock and stain and scale treatment. Is there anything else I should be adding at that time, or maybe not add anything? BTW, it's only a 225 gallong tub.
