Green Bubbles???

[gobyfan]

I just have noticed that there is some green small bubbles on my filter and some of my equipment inside the tank. Is this Bubble Algea??
Is this good or bad?
I have a Emerald Crab, but i dont know if he will do the job!

I once heard that these things multiply. I Also have spoken to a pet store owner who said that he actually plucks them out of the tank.

gobyfan,
Could well be valonia [bubble algae]. Interesting and even decorative stuff. It can, however, spread quickly so watch it. If you do pluck it out, be careful not to burst the bubbles which could cause further spreading. Mithrax crabs love the stuff.
