MY ter is 3 2 liter soda bottles with a rigid piece of airline hotglued into the cap. the ube hangs down 2 inches into the bottle. i have an airline running into a gatorade bottle that has three rigid tubes that are under the water in thegatorade bottle(this is the check valve or bubble counter im not sure). i have another tube that is in the gatorade bottle but not submerged that has a tube running to my tank. the gas from the 2 liters goes into the gatorad bottle, bubbles to the surface then goes into the tank. the recipe i used was 2 cups sugar 1/2 teaspoon yeast 1/4 teaspoon baking soda. i added sugar and soda + liter water. shook it really good, added yeast sealed it and waited an hour then attached it all together. my issue is im not getting enough gas to get a single bubble in the tank. i can see bubbles rising in the gatorade bottle but it obviously isnt enuff to push out into the tank. im pretty sure i got good seals so its not leaking out.what is wrong?
