Question about my tank

Question
I have some green bubble looking things all over my live rock? i was wondering what they are? i have some polyp coral on the rock as well!! are they just more of them starting to grow? if s how long will it take for a coral to come out?

Answer
Hi Casey. What you have growing in your tank is green bubble algae. The easiest way to control this form of algae is simply by manual removal. Try to gently pick the bubbles off of the rock that it is growing on. If you pop it you run the risk of releasing thousands of tiny daughter cells that will each form a new bubble algae. Don't be too concerned though if it does pop. This algae is very easy to control and usually does not populate a tank enough to cause a problem. If any new ones form just simply pick them off. Emerald crabs find this algae very palatable and do a very good job in controlling it.
