"Hi scapes can explain further why need to get rid of the grape caulerpa... I seen your thread, excellent tank :inlove: ,
hope to learn more from you"
You have a VERY nice tank. You said you saw in it my thread...i'm in the process of removing it. It's way too invasive. I realize I'm in the macro thread here, but there are other less invasive, more desirable macros to have i.e. the red kelp you got. very nice. the grape caulerpa has rooted itself into my rocks, grown over my zoanthids, grown through my other macro's, etc...of course it's your tank, you can do w/ it what you like of course, just speaking from my experience.
oh, it also goes sexual. meaning, it will cast a powdery light green tint to your tank. once that happens it will all die and all must be removed immediately. I don't know the factors as to what causes this...i'm sure someone will chime in here and explain it to us all....but this is just one more nuisance of this algae.
