ha ha ha ha NO SMELL put it back and let it age awhile longer. No, really it all depends on what the skimmer is taking out. If it is more platonic bio-mass then it stinks more than if it were just fish poo. My skim mate really stink most of the time but there are times it does not seem to have much of a stink at all. I chalk it up to a few things possibly my head is a bit stuffed up, head cold weather is changing. The change in weather can do this sort of thing as the air pressure increases it put more pressure on the surface of the water and there for keeping more of the solids lower in the tank there for they do not go to the sump. Fish poo alone does not stink to bad because it is already partly broken down. there is a stink but no were near the stink of taking live bio more out and letting it start decay.

If you don't believe me then take a small tank set it up and get it running for even a couple months and then drain the water out and wait and see what the stink will be like.
