Benefits of DIY CO2

Yup. Finally my DIY CO2 is producing CO2 constantly throughout the day.

I start to see O2 bubbles produced on the plants. This is the scene I loved the most because it is just marvelous, how the plants can breath and photosynthesis. It is a beautiful scene of God's creation.

So what's the benefits?
1. Plants is able to photosynthesis better. (Without the CO2, I never see any O2 bubbles)
2. Plants is growing faster. Hopefully not inviting algae. =)
3. It is cheap to DIY CO2 because you don't need a specialized tank.
4. Lower the pH of the water, everything in the tanks seems livelier than before.
5. My fishes too. There were some mucus on the tetra's stomach and spread to few tetras. After the constant release of CO2 into the water, the condition has improved.
Slowly seeing mucus on the Tetra's stomach to diminish.
6. Using it with Flourish Excel is no harm, of coz you must follow the suitable dosage daily.

So, are you thinking to DIY your own CO2? Try today! Get your ingredients and tools ready!

DIY CO2 Part 2

CO2 in the making in the bottle. Finally got the mixture right. =)
With the same recipe, I will update again on the duration of CO2 it can produce. Watch this space!

The stuffs needed for the DIY CO2:

1. Used Water Bottle (preferred 1.5 ltr)
2. Glue gun
3. Instant Yeast
4. Sodium Bicarbonate (Soda)
5. Bubble counter
6. CO2 diffuser
7. Measuring Spoons
8. Small air valve
9. Air pipe , preferred transparent type
   
10. 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.

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.
