lights power consumption

Are you running the PC's for the sunrise/sunset effect? If so, that is not absolutely essential, so you could remove the PC's. If the PC are for actinic supplementation, you can always just switch to higher K bulbs. Growth may be slower though but you will save on electricity costs. That's what I did. I was running a 250W and 2x65W PC for sunrise/sunset/actinic but wanted to save some on energy consumption, so I removed my PC's. I noticed no difference in behavior in any of the corals or fish or anenome once I stopped using them.
