Hi, can someone help ID this algae and let me know how I can get rid of it (other than water changes and phosphate filters)? It came out of nowhere, I haven't introduced anything into my tank in many months. Thanks!
I know I'm a bit late to the party, but Michael is correct, as usual
What kind of live rock do you have? I have the same algae from aquacultured Caribbean rock. I actually don't mind the algae as it doesn't get out of control in my tank and adds something different to the tank.
It's an interesting macro for sure. In my tank, each individual stalk doesn't seem to be long lived. New stalks crop up, die out and others crop up...lather, rinse, repeat.
I have noticed that when I change out my GFO regularly (yes, I've been horrible at maintenance the last year or so) it (along with the Codium sp) will disappear for a while. If I don't change the GFO for a while, both macros will make a pretty good comeback.
