I recently moved tanks, 100g -> 120g. In the new sump the down pipe and the return pump are located on one side of the sump and the EuroReef Skimmer is located clear on the other side of the sump. Its not a terrible huge sump ~40g.... Now my EuroReef Skimmer doesn't produce any waste... Is it because the input and output are so close to one another and the skimmer is not getting "new" water to skim? Has anyone experienced this before? The tank has been set up for 3 months now.. Corals are doing well, fish too... additionally it should be noted that I feed a ton. Everyday a mixture of Cyclopeeze, formula 1, reef formula, phytoplankton.... Shouldn't I be skimming something????
