 No, I can walk into a house and know Prime has been used within the last 2 
or 3 days. If you are sensitive to sulfur compounds -- not all people have 
the same sensitivity, and the sensitivity can vary from compound class to 
compound class -- Prime is not a good product to use. I have recommended it 
to a lot of peple, particularly people who are starting new tanks, but I 
don't use it because of the odor. YMMV.
 The threads you cite and the ARG website talk about Amquel Plus not 
sequestering nitrite and nitrate ions, and Kordon manufacturing Amquel (not 
A+) after the patent expired rather than buying it from the inventors, ARG. 
With regards to the patent expiration issue, see generic drugs. No one 
disputes that Amquel destroys chloramines and converts chlorine and ammonia 
into nontoxic forms. Prime sequesters nitrites and nitrates but according to 
the label you use 5 times the normal dosage to do so at meaningful 
concentrations. How many mature tanks with high levels of plants contain 
either of those anions unless they are added to the tank?
 I'm fine with people prefering different brands, products and 
manufacturers. I think the original assertion was that some unspecified 
products leave toxic forms of ammonia and chlorine behind when used to treat 
chloramines. I would think that if that were the case we'd have heard about 
deaths from chlorine and ammonia poisoning.
