I got locked in my room once... Luckly the curcuit breaker for the house was in the same room. I just turned off power to the whole house so someone would come open the door.. Took a few hours till they got home but hey they know something was wrong when they had no power
LOL, it was a present from my dad. Didn't really set it up since I was focusing on my larger tank.
I just rinse it a few time with water and add some water to let it soak over night.
