Does Flourish Excel stress/kill corys!?

I just had a green cory die, and I am wondering if it could be because of Excel?
I have had these corys for two months- four green corys, still fairly little, but have grown alot since I got them- now 3 corys I guess :( , anyway, I started using excel about six days again with the beginning dose and have put in 1/2 cap in every other day since. I have a 38 gal, with other fish that seem to be fine. I have a thread running in the Catfish/Bottom feeders forum, (with more details) but thought this might be better for info on possible side effects of Excel- PLEASE go to the catfish forum and help me out if you can!!
 
I've dosed up to 3mls. of Excel daily in a 10 gal. tank for weeks at a time, with no ill affect on my Corys. Also, I inject CO2 into that tank.
May have just been a co-incidence losing the cat.
