in my tank i have one of those hollow rock/tree trunk things that hold filters, heaters and stuff
and on the side there is this grill/grid thing that sucks up the water(its pretty powerful) so i put my co2 canister to a tube with an airstone at the end right next to the grill. so im hoping that by the time it comes out the filter waterfall it will be dissolved, will it?



P.S. it seems that when i turn of my light my fish start gasp a lot and bottom dwellers go to the top trying to breath air. should i put in an airstone?

now instead of of all this yeast,suger, water businesses could one just get a co2 tank(like paint ball tanks) and a regulator and just stick a tube from that to the aquarium?

Depends on your reactor diffuser method. I've gotten 20 ppm using a hagen ladder with 1 bottle, when I used two I got about 35 ppm.

cool....somethig useful. DO i dose the same for Nutrafin?

Dear John
I am new and very interested to try out your diy co2 . But how big is the cup of sugar ? I want to use a 5 litres container , can you guide me through on the amount of ingredient required ? I prefer to have a longer lasting co2 ( about 4 weeks , possible ? )
Thanks .

Thank you for this

For the Hagen Nutrafin Canister:

Sugar to the bottom inside line,
Water to the top inside line,
1/8-1/4 teaspoon yeast
1/4-1 teaspoon baking soda

Close as tight as possible and enjoy.

The placement of the hagen should be under good circulation as to spread the dissolved CO2 around, and maybe catch the escaping bubble. Not to worry about catching that bubble, since the bubble gets about 85-95% smaller as it travels the rungs, giving you very good dissolution.

John => Thanks & dah! I should have thought of blowing through it to make sure it faces the right direction. The picture is a nice help though too.

re. tubing, I was at a local aquarium club (LAC) talk a while back where the speaker recommended the silicone tubing over the clear vinyl (according to my notes), but I could not remember why so. SO thanks for the info on both kinds.

re. baking soda and limiting/controling the reaction, it does seem that many municipal water sources are hard enough. As I remember it, alcohol, which is produced by the fermentation process (that we are using to supply DIY CO2), is the more limiting/controlling factor. Affecting the constancy more and even killing the brew over time.

Hi beaucon,

Can you share your diffusing method?

Thanks for the info!
Cheers

On the Hagen Nutrafin ladder, I tilt the ladder to trap the bubbles. I figure, why waste them. If I could figure out how to get a nice looking (clear) cup like thing to go OVER the bubbler and trap them for good I would.

Then they would dissolve 100% - correct?
