Here's a little light reading that might fill in some of the blanks of the aforementioned ATS picture. Simply stated, they cannot and should not be used alone if used in a closed (aquarium or biosphere) stony coral system. There are ways to remove these compounds from solution - activated carbon, heavy skimming, whatnot, but they still need to be removed. As part of complete filtration package, they make a great addition - but if used, you have to take the systems approach.
Competition induces allelopathy but suppresses growth and anti-herbivore defence in a chemically rich seaweed (what did I say about spelling in relation to location?)

Hey, how a round of applause for these unsung heroes of the reef, the herbivores and their compatriots?
Corals Chemically Cue Mutualistic Fishes to Remove Competing Seaweeds (this one is pretty neat – really, and may be an argument against using an allopath removal agent)

Ah well, all for now.
