Well I got sick of our growing power bill caused by our lighting system. So I decided to modify my light. I took my 3’ Aqua One (over an AR850) with 2x150w MH + 4x18w F (small by most standards) and added 3 digital timers (internally) to it so I could stagger the way the lights came on. I know that not everybody has access or knowledge to perform this, but the effect on our power bill was for us, significant. The whole thing cost me $40 in parts and is saving me more than that a month in power. I am happy. And besides, I concur with some of the other arguments, there are some prices us marine keepers just have to bare. And for the hell of the argument, bring on the nukes.
