Newbie: Green Grass?
 

Ok so I'm just about done my tank cycle. Been through the different stages it says in the book, I'm not at the stage where all my live rock is turning pink and purple(a good thing) but I have this green grass starting to grow. It doesn't seem to be harming the hermits or snails, but its really ugly. Should I be worried or just leave it be? Thanks in advance!!

sounds like hair algae. snails(depending on type) should eventually take care of it. mexican turbos love it but they are large and clumbsy.

wheres the tank, is it getting sun light on it??? and u can pick most of it off, how old are the lights.. and tangs are good aswell

The tank is getting no sunlight, its a 34g red sea. I have modified it to house another 65W compact florescent and all bulbs are 3-4mths old, but it seems to be growing quite well.

i had the same issue with my rsm when i started it.
