Canister filters are meant to be below the water level in the tank (they work on gravity), so no, they're probably not the best choice for a stock tank. That said, some people do use them with stock tanks, me included (I bought the XP3 long before I got the stock tank and had been using it on a tank where the filter was on the floor below it initially). They can be made to work with some adjustments and keep the water clear, but they're still noisier than they would be if they had been below the tank and are harder to prime. A pond filter would be a good choice for a large stock tank.
