Tank is in La Habra, CA was in Pensacola, FL before that.
If you can find any reefing clubs in the OC or North San Diego Country area I'd love to hear about it. I found two on facebook, messaged them, and have heard no response - I'm assuming because the clubs died.
Anyways, as for the chiller, IME a chiller is not necessary if the temperature of the room the tank is in is kept at a reasonable temperature and there is air movement over the tank.
Granted, if one has sensitive livestock, this won't work. The only corals I have are softies, so they can tolerate a temperature swing.
Many reefers seem to forget the ocean does actually change temperature, season pending.
