Do you have a powerhead in the trashcan to circulate the water? If you don't the water will become a stagnant smell.
I had the same problem. I put in a powerhead to circulate the water (make sure to agitate the surface), and the smell will go away. At least it did for me.
Figured you are a habs fan so I left you a present
