The only way to go! DIY CO2 Reactor

CO2 ingredients.

2 liter bottle.

Fill the bottle with lukewarm water 2 inches from the top.

pour it into a bucket.

add 2 cups of sugar, and dissolve it.

and 1/4th teaspoon baking yeast. Make sure the temp is within a few degrees of 100 degrees before adding yeast then stir it until it dissolves.

Then pour it back into the bottle up to about an inch away from the bottom of the cap.

Drill a whole into the cap and insert the tubing. (I used an average screw driver (philips) and punched a whole. It was the perfect size) I would use a ladder diffuser on the end of the line. around $10.

Then wait about 2 days and it should be pumping out like crazy. You don't need a bubble counter although if you do make one (I will post that soon) it will prevent the small amount of yeast from getting into your tank.

I will upload a video soon. The two liter will last you about a month. It's cheap and works (perfect combo).

I hope this solves your problem Pm me with questions.

Maybe a check valve if you want...

A fellow I chatted with let me in on his recipe. I haven't tried it yet but I can testify to the results.

for a 1 gallon bottle

i use a mix of:
1 cup white sugar
1 cup brown sugar

1 teaspoon yeast ( the one i used was a redstar brand i think)

3/4 gallon of water

Both have worked wonderfully!
