How do you deal with stinky skimmers?
 

I've got a SWC 160 skimmer and it's really disgusting when dumping this thing. It smells horrible. How do you guys deal with this? I've tried skimming wetter but it seems like it always ends up overflowing. Any suggestions?

You can put a little kalk powder in the bottom of the cup when you clean it. The kalk will kill the bacteria which is what causes the smell.
