HI Guys,

I have noticed that there are small little bubles appearing on the live rocks of my tank. What does it mean. My tank have been running for about 5 months.

I think its a type of algae. Correct me if i'm wrong.

Is the bubble big and greenish in colour?

does it look like a miniature bubble coral thingy...small and dark green in colour? Do you have a pic of the bubbles? it could be a kind of algae...not very ugly...but may spread to your your corals...a nuisance....can only confirm if we get to see a pic of it...

It is just a tiny bubble... colour not noticed... It wasn't there last week...
