Thought I would let you know that I am also from the dallas area and would be happy to kind of show you around the hobby. I had someone that helped me get my feet wet back when I first started (12 years ago) and I would be more than willing to introduce you to a few of the local clubs as well just help out when ever you need a quick answer. These guys on here are great...a wealth of knowledge but nothing is better than having local guys to share your newest find (or problem) with. The club my wife and I go to will get together at least once a month and trade frags
and also host DYI classes that are great for building projects that you would other wise pay a fortune for. If your looking for a large tank, I know a guy that is selling a 200 complete with lighting...its reef ready...might be worth a look. Email me if you like.
Also..check out the link in my signature. My wife and I host a site that is intended to be a quick reference for aquarist of all levels. It doesnt replace a message board like this, but its a good resource especially for new hobbyist.
