I just found a free fish tank on the side of the road while going to my buddies house this morning. It is a fifty gallon tank. It looks like they either had mice, rats, or some kind of animal like that that uses that chipped wood as bedding. I was wondering if anyone knows what i can use to clean the tank out so I can get some fish in it within the next month? I have it soaking with water in it right now. All of the seals on the tank are in great shape. I just want to be extra careful before I put fish in the tank. Thanks.
