Its still not skimming today. So it has been three days that there is no sign of it skimming (I reinstalled the sump Wednesday). I moved the cup up becasue it was set pretty low from before. Could the silicone or pvc glue be affecting the skimmer? Im used to the skimmer stopping from feeding the tank, it never really stopped from my hands being in the tank before (i paid attention). I have a bunch of new parts and tubing that connect the tank to the sump, i also added a phosban filter. I took some pictures but the camera batteries crapped out mid shoot, so im waiting to recharge.
Im also concerned about the amount of bubbles coming from the sump inlet. it goes right into the skimmer area of the sump.
