Since I found this forum several days ago I've become very overwhelmed about what I don't know. In fact, I'm surprised the livestock I currently have is still swimming. Some of the equipment people mention don't sound familiar. Is there a site I can go to that will give me a diagram of exactly where the equipment fits on, in or below the tank and what it does specifically. My wife bought me a 55g tank for Christmas last year and I just kind of jumped in with little knowledge of a Marine tank, only limited advice from a neighbor. I obviously lost quite a few fish early on but my tank has really seemed to stabilize over the last two months. Any help you can offer is definitely appreciated, I just wish I would have found Aquarium Advice 8 months ago. Thanks!
