There seems to be a consensus, and I saw a thread on a plant website 
where a Seachem rep confirmed that some plant species, for example, 
Vals, Anaarchis and Riccia were sensitive to Excel. I do normal Excel 
dosing in my tank and my Jungle Vals do seem to have some melt, although 
they have not completely been killed.  I think Seachem recommends that 
you could dose every other day, and I also read some experiences where 
Vals were melted by Excel, but appeared to get "used to it" amd growed 
back.  One theory is (and I am by no means a plant biologist) that the 
affected plants are "simpler" species and thus more sensitive then more 
advanced plants to the active ingredient in excel that appears to kill 
and inhibit algae.
