I thought that you were referring to your 5 or 6 gallon "container" that you bring the water home in. If you are putting it into a larger holding container, then yes, you can put some kind of powerhead in there to keep it circulating, and it will last for a very long time. But if it's just sitting in the small container, not moving, it will become stagnant and you will have to throw it out eventually.
