I just installed the Coral Life Turbo Twist 12x (36watt) UV
Sterilizor on my tank. The problem is I dont see any light emitting from the unit. This unit does not have a window like other units so you can see the UV
light working. My guess is that the way the unit is designed prevents you from seeing any light, since I know it is getting power since its small ballist is warm.
I tested the unit before I installed it with the cover off and the UV
light came on just fine. Anyone else use these and notice the same thing?
