The bottle needs to be warm at all times to keep the yeast active. Try covering the bottle with a hot pack, which might work. I have my whole setup on the terrace outside. So during the morning when the sun comes up the mixture gets warm and co2 production starts in earnest. I have also notices that the best depth to get most bubbles is by placing the air stone about 3”-4” inches below the surface of the water. i grow all my plants outdoors in the sunlight and then place them in my tank. This works for me.
How to check for leaks:
Try this after 4-5 hours after setting up the mixture. Where ever there are joints, wet the surface. Shake the bottle; this will release the co2 that is dissolved. You will see bubbles or hear a “fizz” noise if there are leaks. If there are no leaks then you should see bubbles coming from the air stone.
If there are no bubbles coming make sure that the Temp of the bottle is around 30-32 degree centigrade and try again after some time. Cold temperatures make the yeast dormant so there will be no co2 production.
let me know if this works....
