Its been hell the last couple days with my 75g. The skimmer overflowed a couple days ago, and I had to empty the tank and dry the carpet underneath. I got the tank back together and completely filled, today. After that I noticed the airline on the skimmer was dripping water. I cleaned that all up, and I keep getting a puddle on the stand in the back right corner. I can tell there is still water underneath the tank but I'm afraid the tank is leaking. The water level hasn't gone down in the last half hour, but I'm going to keep checking it.
