I dont know alot about it but I do know more amps equals less draw which equals less heat and friction on a visit to the codfathers house i seen his set up and he had it wired to a 220v system the pump was virtually silent not so much as a hum he told me that wired to a 110v that pump was screaming so he wired it in to 220 WOW that has got to be the quietest tank ive ever heard:mrgreen my vote goes to 220v because noise is always an issue
