So I got a bunch of free gravel from a friend of mine who was changing their aquariums around. I got enough for a 40 gallon tank but I only have a 20 gallon. I'm using this as material to help kick-start my cycling process with good bacteria - can I keep the excess gravel? For how long before the good bacteria wont be there any more/will die off. Right now it's all in buckets of water.
