If you smell a swampy smell it's most likely blue green algae and you'll probably want to dig it out. I hate the way that stuff smells! It might even be an indicator that your substrate is to wet as well.
I've had much better luck with moss that I've found growing on wood already. You may want to give that a shot. Looks great in my vivs!
