Hello,Im new to the hobby.IM just woundering what kind of guides there are out there.Thanks

You'll find many, many "how to" guides on starting a marine aquarium. Sadly, most of them are significantly outdated. That's not to say they don't have any useful information, though. Just keep in mind that technology and philosophy in this hobby change almost as fast as the water. Read everything you can (printed and online), support the LFSs, and especially join OMAS. We'll help educate you and get you pointed in the right direction.
