Skimmer Problem

I have a new system that I started about 6 weeks ago. It is a 29 gallon display with a 10 gal sump/refugium. Not sure if it matters much for this issue, but the parameters are 1.025, NO3=0, NO2=0, NH3=0, 78deg, PO4=0, and pH=8.2.

I set the tankup with established live rock from an established 55 gallon that I have at my parents house, so there was very little cycling. When I moved the tank I brough a few fish, 2 chromis and a lawnmover blenny. I also have a small frag of star polyps, 6 polyps of candy cane coral, a small stalk of xenia, as well as a fair sized clean up crew, 6 nassarius snails, 5 black mexican snails, 1 turbo snail, and about 12 blue legged hermit crabs. I am using a Aqualine protein skimmer, it is the sump model for up to 75 gallons. It is sitting on a stand in the inlet part of my sump in about 5 inches of water.

Anyhow, this morning I got up to catch a flight and went down to check on the tank. All seemed well, skimmer skimming, pumps running, snails snailing, etc. About thirty minutes later I went back through the room the tank is in and the return pump to the tank was cavitating, that caught my attention and as I got closer to the tank I get a nice wet feeling in my socks. For some reason my protein skimmer water level had raised itself very high and water had overfilled my drain on the skimmer. I had to readjust the drain on the skimmer down nearly 2 inches to reset the water level in the skimmer to get it back into production.

Anyone have any idea why this would have done this, I had not added makeup watter or food since last night.

Sorry for the long post.

You might have to raise the skimmer up if it isn't already.

The skimmer is in about 5 to 5.5" of water. The thing that bothers me was the timing of the flood. It had run fine since last week making decent skinmate, then for no reason the water level in the skimmer went out a couple inches. The fact that it happened several hours after the last time I touched anything on the tank is what gets me.
