Im a little concerned about my hard water as well... I have a new FG pool and am wondering if I want to get my water to 200-250 at least to avoid some white marks around the top of the pool.

OK, what is current calcium hardness of pool water and what is calcium hardness of fill water?

Really depends on what those white marks are from - an oxidation issue or scale. The TFP Recommended Levels - Trouble Free Pool page does list a min CH of 220, mostly to avoid potential staining since most of today's pools are not fabricated with calcium. Some test results may help. Maybe a pic of the white marks as well.
So I dont have my cover on just yet (auto cover) once thats one I will fully balance the pool to proper levels, remove those with a little bleach/water and see what happens... ill certainly post again if they come back
