Why does my local fish store try to get everybody and their mother to set one of these things up? I’ve had a saltwater aquarium for quite some time now, and to tell you the truth, it took me a couple years to fully get a grasp over what I was dealing with, there is a lot of stuff that you need to pay attention to when setting up one of these aquariums. I just don’t think they are for everybody. I’m not saying that it’s a bad thing for somebody to set up saltwater aquariums, but it’s just not a good idea to assume it’s as easy as having a goldfish tank either.
