I jst found the best DIY c02 diffuser!!

I tested this method with DIY CO2 and it worked fine at first (small micro bubbles) but after one day came a macro bubbles.
 
I'd be skeptical myself being that cigarettes are involved. By that you would have to take apart one to get the media. No telling what all it has came in contact with prior to and during packaging of the tobacco. But a very interesting idea to say the least. Would definately like to hear more on this.
 
sorry I've not commented further in this thread....here are pics of my co2 setup with cig filter diffuser. I've had zero problems and the size of bubbles depends on how much filter is in the tube, more inserted will create smaller bubbles...if your bubble size increased I assume some of teh filter has slid out somehow. I have two DIY setups in the tank one has the bubbles releasing under the HOB filter discharge so they get blown around and the other had the bubbles released inside the cave thing so they collect under the cave and have none released to the surface...it's doing much better than I ever expected!!

Thanks Stillhumm. May be I did not make it correctly - will try it again.
I have tried many stuffs so far including infusion set as bubble counter.
