Say you got a new aquarium. They use 1000 watters and all kinds of pumps and such. I guarantee you if you say you got a new 200 gallon aquarium they wont ask anymore. They need at least 8-12 hours of light so that will cover the long lengths of time of the light being on. Make sure you tell them it is MH though. I know you said you have HPS, but HPS isn't used for aquariums.
