Skimmer overflowing + Coral warfare issues ???

[Reef Pilot]

Interesting.... Mine has been doing that a few times lately, too. I have been adding new corals, though, and I think all the gluing, new frag plugs, cement and putty is what has been doing it. I just make sure that it is dialed low enough so that it doesn't overflow. Just the same, have found the cup nearly half full a couple times, even with the skimmer level down low.
