Your best bet is to try to find a local, or semi-local reef club. ReefCentral.com usually has listings of local reef clubs for each state. I don't venture over to that forum very much, but if there is a club in your area, chances are good that they're on RC and probably have a link to their own site. Local clubs can usually tell you where the best stores are, sometimes it's just a local guy who deals from his house.
