Now that you mentioned the red thing, mines are true red tinfoils (twinbar with the black on the fins). I've noticed the last month that when the lights out they are deep deep red and brilliant black, and the lights come on and this is the case for about 10 mins then they look very faded and stay this way until the light goes off, repeats every day. My light is only x2 30 watts and its probably less bright than your aquarium by a slight amount. I don't get it...
