I received my Coralife protein skimmer today, hooked it up on the back of my tank until I get my sump built, and started it up. The skimmer came with pretty nondescrpant instructions, and since I've never used a protein skimmer before, I don't know how to calibrate it. That being said, when I started the skimmer up the bubbles bubbled over the cone, and would fill up completely with water after ~5 minutes. When I turn the adjustment knob the bubbles stop overflowing for a few seconds then resume overflowing. The instruction said that the skimmer needs to "break in", but I don't know if this is what that entails. It also say under "Troubleshooting" that if water goes into the cup fast to change the water level lower, but I can't seem to figure that out from the instructions or on other places on the internet(Satellite internet is really slow at the moment so I can't jump around a lot of pages). Any suggestions on how to fix this or if this is normal?
