Smelly water

Can you tell us more about your tank? Size, bioload, last water change, skimmer, last test results...

Either way, you should probably do a water change.
 
I had a bacteria die off once, smelled awful and tasted like death. A big WC, time, and making sure my skimmer was well tuned got me back.
 
The offical procedure.
