The stuffs needed for the DIY CO2:
- Used Water Bottle (preferred 1.5 ltr)
- Glue gun
- Instant Yeast
- Sodium Bicarbonate (Soda)
- Bubble counter
- CO2 diffuser
- Measuring Spoons
- Small air valve
- Air pipe , preferred transparent type
- Measuring cup for baking (Not in picture)
Poke a hole through the bottle's cap using screw driver and inserted the air valve into it.
Bottom view of the cap.
CO2 diffuser with anti-backflow valve. *Anti backflow valve removed as it will hinder the low pressure CO2 gas from reaching the CO2 diffuser effectively.
Managed to DIY all these last night and test the recipe and i works. Took about 1 hr then I see the small bubble flowing in the bubble counter. Yay!
But it is not yet diffusing in the tank yet, as it takes another few hours to build up in the bubble counter bottle and pump into the CO2 diffuser. Shall see the result tonight.
Follow up on this development:
The 1st CO2 mixture was a failure as I used wrong quantity of sugar. It caused the reaction to be slow and short-lived.
Then I re-do the CO2 mixture with correct quantity, within 30 minutes, I see CO2 bubbles forming in the bubble counter.
And for the next half hour, I start to see CO2 released into the water through the CO2 diffuser.
Success on the 2nd try!

Another update on the CO2 brew: The recipe will last you 9 days of CO2 supply, after which you need to brew it again. Took me 5 mins to prepare it, getting pro! haha.
