I think i have a very small leak in my Aquarium...HELP!?

Ok so ive had this 10 gallon aquarium for two days, it has been fine up until tonight...Now i had spilled i little bit of water down the backside of the aquarium, so i dont know if some water got under it and its now just running out, or if i have a seep in the tank...I know for sure the water is comming from underneath and in the front right corner...Also the tank is not leveled perfect, as i did not notice it wasnt level until after i filled it now it wont budge...Please help me :(
