I got this from a guy that I gave some fish to. He had 2 of them. It is an old soup container.
Holds temp great!
I got 11.5 pounds of grain and almost 4 gallons of water in it.
I would say that it is maxed out at these amounts.
There is also a hole in the lid that allows me to stick a long stem thermometer in it, too.
I think I'm gonna like this lil sucker!
