Little White swirls on glass???

[wagirl81]

In the last couple of days I have noticed a ton of these little white swirls on the tank glass. when I look cloose it almost looks like a tiny tube worm or somthing. The bigggest one is mabie 1-2mm. I have tried to scrape them off but they dont seem to come off that easy. Anyone know what they are?? or how to get rid of them?

When my tank was only about 6 months old, I had a bunch of these things appear on my glass and rock. You couldn't just brush them off either, they had to be rubbed or flicked with a fingernail. Very small like little stone circles. I kept cleaning them to the best of my ability for about 4-5 weeks and they stopped appearing.
I never did figue out what they were but if I have what you have then they look like tiny white snails. I wish they were snails! But alas they are not.

Probably
I finally found a good use for the plastic ***** membership card. Use it to scrape off dusters & Vermitids. It also works on that pesky coralline that tries to grow on the glass.

"On the glass of my tank, I can see small, white coils that are about 2mm across and have tiny hairs sticking out. What are these guys?"
"This is probably yet another tube-dwelling polychaete from the Family Spirorbidae. It is yet another harmless filter-feeder that is common in reef aquaria. It is common for these worms to inhabit areas of high water flow, including your tank's plumbing. They readily reproduce via sexual means and often spread throughout the tank, and can generally be considered a sign of a healthy maturing tank."

I noticed that I had the same thing in my skimmer when I was cleaning it one day.....it may be salt deposits. You may want to check your salinity.

Ive had them for a month in my 70 FOWLR. They came in on the live rock.
When I cleaned out my Fluval, I found that they were growing in the fluval sponge filters like a refugium. Next time you clean out your filter, get rid of them in there to. They're stubborn; I still have mine.

peresonally i think they sound like either what broomer has mentioned, or foramiferan, there are a couple of types, and the ones we had resimbled what you are describing, they are difficult to get off, but once we scraped tehm off, our scooter blenny loved picking them up, not to mention some of our other fishes too
