Probably a longshot but I've got a 425 GPH Koralia powerhead:

And I'd like to trade it for the 240 GPH version. Just looking for a smaller powerhead. Mine is only 5 months old. I'm up the coast from Vancouver so we'd have to arrange something for when I'm down in the city or arrange shipping. No rush.
