I would look on marinedepot.com to
See the write ups on the pumps. I'd look at a maxi jet, because I think they are more energy efficient and can still do your amount of water flow, if it was over 1000 gph then i don't think maxi jets go that high. Though I mentioned reading some write ups because on most websites now they list the watts of each model. It would be a pain to look at each individually but if you wanted to just compare a few it won't take that long.
