Let's talk about skimmers

Mike, I think the "faster" part is important. If I'm doing large water changes every x days, and skimmer A is faster at removing than skimmer B, then by the time I change water on day x, I end up with less TOC in the water column. No?

I also agree that a tall airstone driven skimmer will outperform any other under tank model available.
