I'm seriously considering selling my Deltec AP600 and picking up a 9010 I know, GASP, sell the Deltec?? But I could use the money from the difference between selling the Deltec and buying a 9010, plus I'm getting a little tired of an external skimmer. My Deltec has flooded my stand three times, and unfortunately won't fit in my sump, but the 9010 will. Anyway, the waterlevel in my sump is 13", but I see the max water level is 11" Could I just set the skimmer on something, or hang on the rim of the sump like I would if it was an in-tank skimmer? (sump is a standard 20g glass tank, with baffles).
