Little hard white rings?
OK, another Q. I have these little rings all over the walls, my skimmer, pumps. They are about 1mm or so in size, hard like calcium or something? but rings. My camera doesnt take that good a close up shot to show a pic.

Ha!
Yeah, they are fine, they are filter feeders....if in time they, and other calciferous worms begin restricting flow you can scrape them off but that's in years and years....They are reefsafe
