"I am sure Diana Walstad in her book exaggerates the prevalence of true
allelopathy in planted aquaria"



The problem with determining whether or not alleopathy is happening 
in a tank of mixed species is that one has to work out a method of 
having a control tank, e.g. one that has all the same species, but 
which doesn't allow the allelochemicals to accumulate.  I wonder if 
ultraviolet sterilization would also destroy allelochemicals---at 
least those in the water column.  Does anybody know anything about 
this?
