Anyone come across one of these before? http://en.wikipedia.org/wiki/Condylactis_gigantea Apparently it's exudates kill filamentous algae (and other algae types) http://www.jstor.org/discover/10.23...uid=70&uid=4&uid=83&uid=63&sid=21104101151307 I wonder how many other organisms produce this level of "anti algae nastiness". May be a good enough reason to run carbon in front of the scrubber if it's struggling to get going, or if it fails after the addition of a new coral species etc. Food for thought
This give good sence, as there is a lot of chemical warfare going on in a reef. Perhaps even more in a closed system.
