small glass bubbles

[nutoit]

Quick question. I have been seeing more of these small clear bubbles that seem to attached to or around my bubble coral. I moved the coral about two weeks ago and now the bubbles have jumped over and onto the glass of the tank.They look just like green bubble algea but there are clear like little glass balls.Any ideas? Thank you for your input.

Small clear glass looking bubbles are probably air or other gas. It is very common for patches of algae to produce them. The bubbles by themselves should not be a problem. Also, a DSB can produce some bubbles as well. I haven't seen those yet, but have heard they are normal as well. Keep an eye on them, but unless algae goes wild or things start dying, I don't think the bubbles are a concern.
