Nick and the_anti_honda - The chiller is located just below the tank and on the left hand side. My chiller stays pretty quiet but it's actually a test model I'm running for someone.
skylsdale - I didn't shoot the pics, a friend of mine did (Greg Rothschild - mod on RC). I believe he shot all the fish pictures with a flash. If I tried to shoot the pictures, you would only see a blur of the fish.
