2 words - Bubble King. I just bought one for my 185 and it is pretty darn good skimmer but was also pretty darn expensive so a used one if you can find one. It is almost silent. Maybe a BK Mini 160 or 180 for that sized tank. I agree if you are keeping SPS you need a really good skimmer.

If that is a little out of the price range, there are usually Euro-reefs for sale used that will do a good job.
