Well, whether or not you can use it isn't the question, really. [H] is asking whether or not he SHOULD. That power consumption is pretty high, and the pump might be a little overkill. If you have access to something else, like an Eheim 1250 or a Danner Mag 3, that would probably be a little more efficient. If you have a lot of heatercore area, then the 1262 should be alright.
