What are these??

I was moving things around in my tank and found a couple of perfectly round bubbles that look like marbles. What are these? there were 3 by my queen conch. thanks

Just above is a search button...I'd suggest using the search feature for information about bubble algaes...or valonia algaes...sounds like what you've found and if not dealt with properly they can cause problems.

Is bubble algea a horrible thing for in my tank? How do I clear it from my tank? thanks
