co2?

[aznkonner]

hm...just a quick two cents in on how i did my diy co2. i had a 2 liter bottle (or any sort of bottle really) and then of course sugar water and yeast in taht. a seond bottle i put the tubing under the water so that the co2 would move through the water and hopefully any big particles would get caught by the water. then another tube coming out of that second bottle (so i would have two holes in the second bottle. one for the co2 going in and that one goes under the water and the second leading out and that would be above the water line).

still with me? ok next part is where i think i get lots of good surface tension. i take another small bottle (maybe a 20 ounce) and cut either the bottom of it or just put lots of holes at the bottom of it. then i hook the top part of it to my outflow of my filter (canister filter). then i take the tube where the co2 is pumping out and put it in a place where the co2 goes directly into the bottle that's hooked onto the outflow.

so pretty much as the water is getting pumped into the tank it breaks the surface of the water inside the bottle. once that bottle starts to fill with co2 the filter will be breaking the surface area with only co2 which makes for good diffusion. eventually the co2 will overflow and come out of hte bottle but that's fine because ur yeast will continually make more.

u don't have to use a canister to do this. a normal pump will pump water into a bottle and diffuse the co2 just teh same. i will admit it looks a bit ghetto but if u can find small bottles and if u work on it a bit i'm sure it can look really good. once i get my new tanks set up i'll get some pics of it going

sorry for the delay. i was hoping to get a good camera but i guess camera phone will have to do. my co2 set up isn't up and running so bear with me and use ur imagination.

that's a full shot.

this one a close up of the bottom of the bottle. as you can see i have my tube that comes from the co2 bottle going in one of the many holes i poked into the bottle (oh yea the bottle was upside down in the tank that's why the holes look like it's on top)

and finally the top part. i connect that part to the outflow. so as you can see as the co2 goes into the bottle it gets trapped at the top. water flows in and causes agitation. causing the co2 to break up. for even more agitation add some bioballs into the bottle. as the co2 fills up it will eventually come out of one of the holes in the bottle.

it's quite simple and it sounds real complicated but it works very well. it beats spending 20 bucks buying those pumps that swirls the co2 around. i don't have a picture of the overflow version of this in action but i might be able to get one up and running when/if i make one for my new fish room
