I was just reading one of those little factoids that pop up on the side of the page, this time about protein skimmers. I'd always wondered what the heck they were but ignored them because they're for saltwater and I don't have that kind of setup. On reading it though I thought it sounded like a darned good idea! Is there a reason why they're not used on freshwater systems? Or are they and I've just never noticed?
