algae ID!!

Hoping someone out there has a link to an algae/macroalgae identification with good pictures. I was checking out mt tank last night and seem to have an unknown algae growing between some of my polyp corals. I didn't notice the day before and am hoping it is nothing too evasive that will spread and kill my coral. I tried to take a pic but it's almost impossible to see with my cell camera. Thanks in advance!

 

Ill see If I find another link, but try this for now Melevsreef

 

BEAUTIFUL!!!! Found it in 2 seconds!!! thanks IBM!!! - Melevsreef.com - Caulerpa nummularia - Should I be worried or can I just cut it off and get it out of there?

 

Dont know about that specific caulerpa, but I know that some use it in there refugiums. If you dont like it then take it out. Make sure you dont leave any behind since it will grow back.

 

will do tonight - thanks

 

Generally once an algae has established itself in your tank it will be impossible to get rid of completely. In your case you don't have one of the worst offenders so you are lucky. I don't know what animals, if any, eat that kind of caulerpa but the best way to keep offensive algae gone is through superior water quality. It will always be a constant battle.

 

Caulerpa is actually beneficial, only problem is that it could spread real fast or that it may be unsightly in main tank.

 

It can be. But if you are using it in your fuge you have to be careful and not let it go sexual, lest you risk an ammonia spike. Some of it can actually be pretty attractive too.

Actually, there are some better fuge choices anyway but Caulerpa sp. are commonly used in this manner.

 

Yup, It can go asexual. That's why I stick to chaeto.

 

Someday I am going to try having a mangrove fuge. From what I understand the nitrate uptake is unparalleled.
