I'm pretty sure these spots are new. White spots on my tanning ledge.

I started following TFP about 2 weeks ago, so this could be due to anything in the past when I had the pool store taking care of things. When I started TFP, my CH was only at 175, I've got it raised now to about 300. Could it be this, or something else?
