Anyone use venturi line w/ DIY CO2?

I read some do and some don't. So do you use the venturi line w/ DIY CO2 w/ powerhead? What about using a T valve so half air/half CO2?

Don't give up so quickly. HAGEN and Tetra's have pwrhead with venturis, and I use both. The common belief is that diatomic molecules of nitrogen and oxygen (air) will displace CO2 faster than by CO2 by itself. The pwrhead will also circulate nutrients and clear a cloudy tank faster.

cuz were wondering if the pull from the venturi line on the power head would end up sucking your bottle to a point where u would suck the forumla into your tank.

:\

Also i dont think u'd get a good diffusion though that unless it was a needle impeller which chopped the bubbles up b4 it spat it out.
A ventuari if i remember correctly pushed water and the air line attached would pull air as the water was being pushed out... not suck it into the impeller, chop it up, and then spit it out into the tank.

i dont want to pass out wrong information, so i honestly dont know... but those are the concerns i had when reading your post, and didnt know if they were truely concerns.

I thought the venturi line was the same as the air line?

If attachment from CO2 to venturi is not airtight and preferably submerged, the seal instead allows tank water to be suctioned in and NOT the CO2 yeast solution.
