My Co2 system has worked great. It's been producing co2 for twelve days now. I haven't had any problems with the yeast/sugar water getting into my tank as i have a gas diffuser for that reason. As an added caution.
What you need are: 2 liter pop bottle, another bottle for the gas diffuser ( i used a 32 oz. gatorade bottle for the wide cap), a 20 oz. pop bottle, a pair of scissors, a hot glue gun, some air line tubing, and that little blue thing which is a flow regulator (only lets air flow one way), drill with bit smaller in diameter than the air line, suction cup.
You need to drill 1 hole in the cap of the 2 liter pop bottle. Drill two holes in the gatorade bottle cap. Drill one hole in the 20 oz. pop cap.These holes will be smaller than the diameter of the air line. Next cut the 20 oz pop bottle in half to make the bell where the Co2 will go. Next cut the airline into desired lengths. Then cut the ends of the lines at an angle about a 1/2" long. Now insert the angled end of the tube into the pop cap and pull. Cut of the angled part. I cut this one about 1/2 inch long. Use the hot glue on the outside of the pop cap to seal the hole and hold the air line in place. Cut this line in half and put the flow valve in. Take the other end of the air line and insert it into one of the holes in the gatorade cap and pull. Cut of angled part. I made this line about 3-4 inches long so it will be under the water level of this bottle. Now insert the other air line into the second hole of the gatorade cap and pull. Cut of angled part. I made this one about 1/2 inch long. Glue top of cap to seal holes and hold tubing. Insert the other end of this line into the 20 oz pop cap. Cut off angled part. I left about 1/2 inch long. I did not glue this one. Put caps on appropriate bottles. Cut hole in bell for the suction cup. Finished product will look similar to my pics.
Fill gatorade bottle with water until the one air line that comes from the yeast solution is under water. This serves as gas diffuser/ bubble counter.
The flow valve will keep any access water getting into the yeast solution which will make it bubble over.
Co2 recipie:
3 cups warm water
2 cups sugar
1/2 tsp yeast
1/2 cup hot water from tap
You need to put three cups warm water and two cups sugar into 2 liter bottle. I then shook this to mix. Add the yeast to the hot water and stir to rehydrate the yeast then pour into the sugar water. I then shook again to mix yeast and sugar water.
