Algae growing on live rock?

Hello everyone, my live rock has some kind of green algae growing on it. Is this good, bad, or does it not matter? Is there a way to prevent it? Is it caused by too much lighting or what causes it?

Normally caused by the presence of phosphates and nitros, along with lighting. I wouldnt call it bad if you dont mind it, but if you dont do anything to control it, algae will be everywhere in no time. Best way to control it is by depriving it of its nutrients, which starts by using ro/di water, then you can use an ATS if you still have trouble.

at first when i did my first sw tank i thought it was cool then boom it spread like rappid breeding rabbits... nd now since i got a 300 nd more expericend i equppied my self with a hevy cleanup crew bunches of hermit crabs, the biggest scooter blenny i have ever seen. my niger triggerfish is always munching on my liverock too.

I should also note that poor tank circulation will allow it to spread as well.

very true i forgot to mention tht since i strted using them reef fan powerheads i have zero algae

i just get a toothbrush (>>>NOT USED OR YOU WILL START A BUNCH OF -BLAM!- IN YOUR TANK<<<) and scrub it off

How old is the tank? A new tank will usually go through and algae cycle.
