Re: [GSAS-Member] Anyone successfully using "Seachem Excel" in their planted tanks?

[matt kaufman <igotadose@hotmail.com>]

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.
