I have 2 aquiriums in my work/computer room. One is a 10 gallon that I have a small bullhead (~6"; that I caught when it was less then an inch long) and a small green sunfish hybrid. The other tank is a 55 gallon with some tropical fish in it...that I'm hoping will kick the bucket so I can replace them with native species. Anyway, I was checking email late last night before bed & noticed that the water sounded a little low in my 10 gal. The trickle from the filter was a little louder than normal. I thought, hmmm, I just put fresh water in that a few days ago. I'll take care of it in the morning. Fast-forward to this morning: Sat down at the computer to check in here on the BOC and the trickle from the filter sounded REALLY loud. I looked over & the tank definitely needed some more water. My initial thought was "Wow, that lost a lot of water last night. I'll add some more after breakfast" Then I looked closer & saw standing water on the hardwood floor that ran across the room & into the closet. NOOOOOOOOOOO!!!!!! :crazy::crazy::crazy: Well, everything is cleaned up now. Probably lost 5 gallons of water, most of which ended up in the basement...or soaked into my wood floor. I'm anticipating the warping to be not so pretty:sad2: I'm not sure where the leak is. I have the aquarium sitting in the garage now & it's not losing anymore water. Regardless, I had to look on the bright side! Thank God it wasn't 20 gallons from my 55 gallon tank!!!
