How often do you change bong water?

I empty the water in my bubbler every time I use it, 'cause I have to hide it and its easier to hide without water in it. I like, can't tip it on its side if it has water in it, and stuff.

So yeah, how often do you change the H20 in your smoking device?

Damn, I meant to make this a poll.
