Caulerpa!

[IJC]

Just got back from christmas at my parents place, and in just 6 days the caulerpa (both grape and regular varieties) has really gone out of control. I'm going to have to do some major plucking.

Anybody have any good means of control? I"ve got a yellow tang, and he pecks at it a lot, but is no match for the caulerpa.

How bout some possible problems with my water conditions that I can try and change?

On a better note, to my relief, the auto topoff system I hooked up just a few days before leaving worked great - the level in the sump is still exaclty where I want it.
