Improvised CO2 diffuser

[peterkoh]

Folks, just thot I share a cheap and imho pretty effective co2 diffuser.

Cut a section of 5-6 inches of soft silicon rubber tube. Tied a dead knot at one end. Poke it with a fine needle as many holes as you can. Connect that to your co2 line. Hold it against the glass using a sucker in the tank.

The bubble is not as fine as the glass diffuser but it's cheap and easy to clean\make and take up a lot less space.

I wouldn't call it improved co2 diffuser since the bubbles arent fine. The rationale for having them fine is to have them dissolved before hitting the water surface. That 's what a ceramic disk is for via pressured co2.

Besides, most arista nano diffusers cost no more than $5, looks good and takes little or no space.

Improvised, not improved.

Peter, if space in tank is a concern for you, Dymax have a ceramic atomizer which is really quite small. Its only drawback is that, unlike most glass diffuser, it cannot double up as a bubble counter.

Thanks guys. Efficiency is secondary to me else reactor would be a better choice. I understand that the glass diffuser needs to be clean of the algae often and in most cases have to be discarded as the disc cannot be removed. I can easily tuck a silicon tube in a corner and will soon be camouflaged with algae. I'm fine with the not-so-fine co2 as it's on during the daytime via a solenoid and I've only a 2 ft tank.

Cheers,

Managed to find a video of the dymax atomizer so everyone knows what I am talking about.

Peter,

Can really appreciate your improvisation, wonder if it could be used for DIY yeast co2 as well.

You can try but it depends on the buildup pressure of co2 and water pressure of the tank. When I was on diy, i just let the bubble go into filter inlet or just below the outlet to help dissolve the co2
