White residue on newly painted concrete pool

[oldnewbie]

Thanks for the advice. I called them and they say that since the white stuff will come off it can't have anything to do with the paint. He thinks it has to do with something in the water, possibly calcium. I know our area has very hard water - just confused that rain water would cause it.
Any other thoughts?

Possibly, but I'm skeptical. Unfortunately the guru there that I used to call is retired.

Did you add calcium after filling the pool? How long ago did you paint?

Probably, you'll need to get a K2006 -- not as if you don't need one, anyhow -- and test the alkalinity and calcium levels on BOTH your pool, and the water you fill with. Even if that's not the problem, you are going to need valid test results before you can go back to Kelley and try to get more info. Test kit page link is in my blue signature box below.
