Beyond the lights, I think it's often the big returns that gobble up power on your large tanks.

I am running a good size system and I calculated my electrical cost to be approx. $50 per month. I have used the RC calculator to approximate the cost of electricity consumed. I am very careful when selecting new equipment to ensure that electrical consumption is a consideration. My main system return is an Ampmaster pump and it uses about half of the power that Reeflow pumps use. Tunze product are also very low consumers as well.
