I don't know about you but I'm often so excited to blaze that I don't change my bong water. What's the longest you've gone without changing it? 4 to 5 days for me
I change every time I smoke. Not between each bowl but between each sesh. I would never let bong water sit its gross and defeats the purpose and then it stinks..and looks nasty as heck sitting in there. I dump the water when I'm done smoking.
Yeah I agree its gross any way you go about it, but I should qualify my statement by saying that I'm a light smoker and only hit the bong maybe 3 times a week.
After each session, as I assumed most do... or at least, I'd hope. I feel bad for people using hemp wick on their $500 bong with multiple percs and attachments to only let nasty bong water sit in it for days at a time.
^ Exactly this. I mean come on, it's the obvious best way. I can taste the old ressy nasty water easy. It's not that hard to walk over to the sink after every smoke session.
