I was searching for a good DIY diffuser cause the airstone works but not that great, I came across a thread at another forum and gave it a try.... an unused cigarette filter! just unwrap it and peel apart till it fits in the airline, put about 1/2" into airline and leave 1/8 -1/4" sticking out...it works!!! The bubbles it releases are so timy that most of them are gone by the time they reach the surface!!!
Try it!!

neither are air stone companies, local water company, manufacturers of filter media and on and on :silly: :evil_lol:


One question though... I have a steady steam of micro fine bubbles of c02..actually looks like I am using an airpump attached to an air stone.

Is this too much? how do I control the flow? I hear alot about contolled amount of bubbles per second..do I put more water in the container?
 
You will probably get some milky white smokey looking slime on the tip of the Co2 line with that cigarette filter. Just saying so you know before it happens.
 
Yea powerhead is next on the list but I made the bottles out of boredom and when it actually worked I was shocked. Lol. Then realized I needed something now. It works great though. Have the bubbles going up to the hob filter outflow area so the rise up slowly then get blown all around again I'm losing almost no bubbles to the surface. Btw, guy I read about that used this method changed filter with every bottle change for those of you that are trying
it.

interesting it actually sounds similar to the idea of putting a chop stick into the tubing. my main concern would be it would break don in the water or get gummed up.

In the early 70's at Lake Tahoe we would pick up 100 cigarette butts in trade for a 10 minute ride on the lifeguards surfboard. They would take years to degrade. You could tell what season they came from by the amount of degradation.

I would guess three years or more before it dissolved. Clogging is another matter but if you don't get any yeast in it it should last a long time.
