What are some nice websites to get SW equipment?
I've heard that the best deals for aquarium hardware are available online, but I don't really know where to look.
Do any of you know of a good place to find saltwater tank equipent online and at a good price?
Also, I've been looking at used setups, which are going for very cheap. Is there any reason why I should not buy any of these previously used setups?
Any information would be appreciated.
