Beginner in San Diego looking for good lfs's.

Though I'm a beginner I want to learn as much as I can as well as get
some good deals on my new tank and equipment. Can someone please help me
connect with a good local fish store in San Diego? How about a source
for good used tanks? I'm thinking 72 gal or so. The last thing I want to
do is torture some poor fish with my ignorance. I want to do this right.

Thanks,
Troy
