Coralife Aqualight (the fans in them)
 

Are they thermostat controlled? I just noticed tonight that the unit over my FW tank didn't have its fans running. :confused:

I don't know which unit you have, but the two lamp unit only has one fan. It looks like it has more, but that is a deception. The fan only runs when the front lamp is lit. When only the rear lamp is lit the fan does not run. It is designed that wat BTW. :eek:

Ah ... good to know. Thanks Bob!
