bubble-like pest

[juan jose]

Hi, I´ve recently seen 3-4 bubble-like algae on my display. They are green in color, some have turned white. What are they and how can I get rid of them before they get out of hand.
thanks

It sounds like bubble algae to me. Here is an article http://www.reefkeeping.com/issues/2002-02/hcj/feature/index.php that you might be interested in.
