I am getting started on my 40 breeder tank with a 20 gallon long for the sump. I bought a slightly used reef octopus XP-1000sss protien skimmer at a pretty good price. It is rated for a heavy stocked 75 to a lightly stocked 125. I have plenty of room in the sump. Will the skimmer be effective, or should I look to swap it for something more appropriately sized?
