That's... pretty fucking gross, my friend. Just pour it out into a sink or toilet... and even if you don't have that, just open up your window and pour it out onto the ground below.

I change it after everytime, because I heard that if you leave it in there, it can shorten the life of your bong. Not sure if it's true, but I'm not taking any chances on it. Plus, I just love the flavor of smoking weed through a bong with fresh ice-cold water. That's just me, though.
