an aquaeuro classic 135/250 or recirc 135 would work well on that sized tank, as would an octopus nw150 or nw200 or a smaller recirc (depending on height under your stand)
if you have the cash a tunze 9010 would be awesome, and it is very small (only a 5x5 footprint) can't beat the skimming for the size and price.
