I just started using Prime in the past few months. Never had any odor problems using recommended dose.

If you have any dead spots on the surface, an eddy where food will get trapped there for a few days, maybe some plants will hold it there in one place, and you feed Krill. THAT will cause a serious stench after 2-3 days if it goes unnoticed.
Check the rim of you aquarium. I've had smal pieces of fish and shrimp get smashed between glass and top and boy did it cause a stink! Took me forever to find it too!

try using the pond prime it is twice as concentrated as regular prime I save a lot of money because I have large tanks with automatic drip system,so need to add to tanks every night. And as the other people say there is no smell,so I would have to say that the Pearson who suggested that you check the rim of your tank is on the money. I feed pellets threw finger holes and man does that stink when the food gets wet and builds up on edges
That's why I use Kent Dechlorinator 
Equally potent and efficacious, similar price, but without the stink!

That would be incorrect - they are the EXACT same formula.
Pond prime has different dosage rates listed due to the fact that it is designed for treating large open water systems. This used to be stated clearly by Seachem reps on the Seachem FAQ for Pond Prime.
And HarleyK, last time I checked Kent Dechlorinator is based on sodium thiosulfate, which only neutrazlizes chlorine, not chloramine, so it's actually not as potent and efficacious as Seachem Prime. Sodium thiosulfate can be purchased in bulk from commercial aquaculture facilities for next to nothing.
I have a sticky in this section on this subject - some of you may want to check it out.

You are correct that Kent Pro-Dechlorinator is based on disodium thiosulfate.
You are incorrect in stating that it does not neutralize chloramine. It very well does. The chemical reaction is not too dissimilar from neutralizing molecular chlorine, just that it doesn't act on the chlorine, but it reduces the oxidation stage of nitrogen. Thiosulfate neutralizes chloramine, and that's a fact.
BTW: The European SDS for Prime lists Bicuculline as ingredient. When I add a conditioner, I do not necessarily need to dose my fish with a stimulating plant alkaloid
I'd rather keep it clean and simple and just add what I need to get the job done. Just one of the reasons I switched to Kent years ago...

prime is a salt, hydrosulfite to be exact, it does not remove chlorinates. being a minor neg charge ion it binds to them, there by making them inert for a limited time. for prime that's 48 hours and chlorine gasses out in 24 to 36 hours.
you think prime stinks when you open it, try safe. if your tank stinks it aint the prime.

Maybe it's just the wording used that confused me, but I'm with RD on this one...sort of. I don't doubt that thio will remove chlorine, but it leaves behind the amine group, dumping ammonia into the system. Provided that your water supply doesn't use too much chloramine, your system is probably able to handle the excess ammonia within a fairly short amount of time...but you are still spiking it. Numerous websites will mention this. For example:
"In chloramine, two chloride ions are bound to each ammonia molecule, and that's why you're usually advised to double the quantity of sodium thiosulfate you'd use for chlorine alone. In acidic water, the ammonia released would largely be ionized to its non-toxic form, ammonium. In a planted aquarium NH3/NH4 would be rapidly scavenged by the plants. "

Idk about how rapidly it will be consumed, but ammonia is probably better kept "locked away" with a product like prime so that your bacteria can utilize it without stressing your fish out. Prime still sounds safer to me.
And for the OP, I also only notice a smell with prime when the bottle is open. Is there a chance that you spilled it somewhere and that's what you're smelling? When one of those bottles leaked in my car it took about a week to air it out!
