Thanks for the warning Matt. I was thinking of trying to use some Excel in
my discus tank.

Clarifying. Here's what really happened:
 
The label on the bottle says, "5 ml per capful." I blithely added 5 capfuls.
 
Trouble is, the bottle I have, is the 2 liter bottle (it was on sale.. oh
well.) The cap, as I've now measured, holds *15* ml. So, 5 capfuls is *75
ml* or about 3 times what's needed.
 
Of course, overdosing an aquarium product shouldn't kill your fish, but hey,
since the FDA or any recognized testing body isn't involved, caveat emtpor
and this emptor didn't caveat enough.
 
Nice of Seachem to not get the dosage information right on their damn
bottle. My guess is they just used the same label from the smaller bottles.
 
Something that kills fish at high doses probably should not be used even at
the recommende, low doses.
