I got my set-up used so I am not sure of the brand of some of the items. I do know that my filter system is a Marineland Tidepool 2 but I do not know about the skimmer. My question is, it appears that the skimmer is to be set up withen the sump tank and the water from the main tank drains directly into the skimmer via one of the drains. I don't believe that is the normal sump skimmer operation. It has a Rio 2100 pump that the intake and exhaust fit directly to the skimmer and another tube is used to bring in water. (I will get pics asap). Has anyone heard of this before?
