Noticed there wasn't a thread about this yet so I thought I'd give everyone a heads up!
It's mainly a saltwater show but I'm willing to bet you could find some good deals on lighting systems and tanks! EcoExotic has a booth there, and their LED lights are pretty legit...
Seattle Marine Aquarium Expo
I won't be there cuz I'm working but I've got a buddy grabbing me some breather bags from kordon and maybe another panorama led from ecoexotic.
