Hi Guys,
I have a question for you all.
I just picked up a used 2x2x2 tank that I am going to be using as a top up tank for my 350 gal and I was just wondering whats the best method to clean it as the guy had been using it to bread mice.

I've always had good luck with used tanks using a very diluted water and pure ammonia mixture. Then I washed the tank out 3 or 4 times with water really good to make sure there was no residue left and let dry out.
