Anyone have a bio cube protein skimmer?

I started using my skimmer again in my 10 gallon and when I hooked it back up it starting skimming great then today it just stopped building skimate. Anyone have the same problem or know what I'm doing wrong.

Thanks

Same thing happened to me last week, it's likely because it cleaned up all the easy to get waist (longer bubble to water contact time is needed to get all the organics) which the Biocube skimmer lacks,
