I had this happen to me once. My wifes stupid cat got behind the tank and pulled an airline off the air pump. I found that if you put a loop of airline just above the water line it will prevent this from ever happening again.
I bought a small screw hook and screwed it in the wall just above the water line and looped the airline through it.
I don't even run airlines or air pumps. They're not necessary if you have surface agitation. I certainly wouldn't use them if this happened to me

something about bubbles just does it for me
Quick question... The airline that drained my tank didnt have a check valve. If it did, would it have stopped 70 gallons of water???
