Allelopathy - natural response to physical stress?

I was always under the impression that a coral was always putting out a certain amount of allelopathic compounds but under stress it would increase this. Admittedly this falls under the "I've always heard from other hobbiests" catagory of knowledge rather than "I read it in a journal article" sort of knowledge. I have heard a few things that "they say" over the years that have proven untrue. :bigeyes:

i read this yesterday, you might find it interesting:

That helps a lot, not exactly what I was looking for, but quite good.
In the wide world of corals, I expect there is some of each.
Is there a particular type of coral you are interested in?

If you can read Chinese, you might read this recent review:
Research progress on chemical defensive substances from soft corals and gorgonians. Wang, Chang-Yun; Liu, Hai-Yan; Shao, Chang-Lun; Wang, Ya-Nan; Li, Liang; Guan, Hua-Shi. Institute of Marine Drugs, Key Laboratory of Marine Drugs, Ocean University of China, Ministry of Education, Qingdao, Peop. Rep. China. Shengtai Xuebao (2008), 28(5), 2320-2328.
Abstract
A review. Despite lack of efficient phys. protection in the highly competitive and hostile environment, the marine invertebrates including soft corals and gorgonians can survive mainly relying on their chem. defensive system by a series of secondary metabolites accumulating in their bodies or releasing to their surroundings. The chem. defensive functions of these secondary metabolites were found to serve as antifeedant, antimicrobial, antifouling agents as well as allelopathic substances. Chem. study on the defensive substances from corals and gorgonians is one of the most important topics in marine chem. ecol. The research results could help us to understand the chem. ecol. relationships between corals and their surrounding organisms. The research strategy and methodol. played an edificatory role in the bioactive natural products discovery and new drug lead compd. generation from marine sources. The research progress on chem. defensive substances from soft corals and gorgonians was reviewed with 39 refs. This review focused on the structures of these secondary metabolites as well as their functions including antipredatory, allelopathic, and antifouling activities.

I wish I knew which one it was
I have a big mixed reef, full of corals other local hobbyists keep together also, only my tank shows obvious signs of allelopathy. I'm trying to find a home for my leathers, but I'm thinking it may be a stony coral now.
Running a lot of GAC, using skimming, and using ozone may all help such a scenario.
