Its not like skimmers have been around for 50 years. I felt I was the first guy on the block to use one back in 86. One thing I've found out is most people who stop using them have been using cheap worthless skimmers any way so what difference does it make.
I've seen these threads a hundred times but I can't recall seeing one started by a person who's been using a GOOD skimmer...
A skimmer is a tool, just like a pump, lights, sand, rock, test kits, reactors. If you have a good one you tend to use it, if its crap you tend to find something else.
