Another new pool owner and BBB convert

[ccs717]

Thanks Watermom & PoolDoc! I have read all(?) the material over at the Pool Solutions site. Again, great info!

One other question for now: The vinyl liner, right above the water line, is rather dark gray and dingy. Using a brush or plain sponge on it has no effect. Is there a best practice for how to clean that? Any such thing as a "pool water safe" cleaner? Or do I just leave it alone?

You can use baking soda on a sponge; that works well for removing some forms of black water line grunge. But sometimes, the 'stain' is actually deterioration of the liner, which can't really be 'removed'.
