BoomerD said:The Remora is possibly the best small HOB skimmer available. While I don't think it's very good for anything bigger than about 50 gallons, it would be great for the 26 gallon tank.
BoomerD said:The LifeReef HSVS-2-24 skimmer is a very good one, but will also run in the $400. range...It has the advantage of being easily converted to sump or external use however.
