Horrible smelling fish tank!!!

Question
QUESTION: Hi, its me the one that had the oscar fish problems and you helped me greatly with. I have a fish tank and all the levels are in order, but my tank smells horrible. I can't stand the smell of my fish tank ever since i put prime in the tank it smells bad. I really feel stupid asking you a question even when i'm an expert in the "fish and freshwater aquarium categorys", but i really need help. Only 1 tank out of many smells and it is driving me crazy please help.

ANSWER: Hey Dillon
Don't feel bad!  I'm always learning new stuff or coming up with new problems on my own lol...

What's it smell like?  Prime does have a sulphur smell to it, but it shouldn't be making the whole tank smell.  I use it in all my tanks, and don't have that problem.  

You're going to have to refresh my memory, it's nearly impossible to go and search back through old posts lol.  What size tank, what kind of filter, what fish and how many, how often are you doing the water changes?

Answer
Hi Dillon
You're vacuuming the substrate/gravel real good?  As long as there's nothing dying or rotting(uneaten food) somewhere-check around under any decorations or plants.  Try adding some carbon to the filter, that's usually the best way to get rid of smells.
Good luck!!
