sorry about the slow reply, somehow lost a few subscribed threads. id look into a skimmer rated for anywhere from 75-100 gallons. I know it would make sense to buy a skimmer rated for your tank but the generally accepted practice is to go +1 on your skimmer, which would put you in the 75-100g size range. heres a link for a Bubble Magus NAC 3.5, its rated for 85g and is a reliable skimmer.
