This is taught by bro dragonfly_sg to me.
For one 1.5 litre bottle. About 1 litre water. About 400ml of sugar. Half teaspoon of Baking Soda. I teaspoon of Baking Yeast. Instructions. Pour sugar in bottle. Fill water until water level reaches 6" from the opening of the bottle. Shake the solution until all sugar is dissolve. Drop the 1/2 spoon of BS in the solution and shake well. Find a little container and dissolve the spoonful of yeast in alittle water. When the yeast become a cream colour liquid (it stinks) pour it into the solution. The should still be 6" to 5" of space to the top of the bottle, do not leave too little space because the mixutre will foam after awhile and will flow into the tank if there is not enough space. Anyway after you pour in the yeast, it will stay at the top layer of the solution. Which mean you have a top layer of cream colour liquid and a bottom layer of clear sugar liquid. I don't mix them. I leave them like that and cover the cap of the bottle. The yeast will start to consume the suagr and produce CO2 after about an hour. You can get sugar, Baking Soda (Kings Brand), and Yeast ( also Kings Brand normally just beside the BS ) in NTUC fairprice. Hopes this helps. Cheers Dennis I followed his instructions and setup a DIY co2 system for my 1 feet tank. After rescaping, my E. tennulus and java fern are pearling now...my algae growth seems to be stunted.. I use exactly 1 SAF green cup (approximately= 400 ml) of sugar for the setup only. |

Refer to my earlier posts... they last up to 4 weeks so far. But towards the end, bubbling gets less intense. Intense bubbling will last at least two weeks. Also frankly I'm not so sure about the role of baking soda. Cuz yeast ferments sugars to form CO2 and alcohol under anaerobic conditions. Baking soda is essentially sodium bicarbonate and reacts with acids to form CO2. If no acid is formed in the process, baking soda should not be able to contribute to the CO2 production. Unless the sodium bicarbonate is used for its buffering capacity which I doubt has any function in this context. Any bros like to clarify on this? By the way sugar if too concentrated will also inhibit the growth of yeast and hence will not work. It is thus very difficult to put alot of sugars and expectthe solution to last for very long cuz CO2 probably won't even appear due to it "preservative" effect on the yeast which will stay in dormant form and not grow at all. Find the optimum concentration for yeast to grow and not overdose the solution with sugar such that it reaches inhibiroty concentrations. Alternatively use sugar alternatives like starch etc. which the yeast can break down overtime and utilise the sugars released in a time release fashion. Another inhibiting factor over time may be the accumulation of alcohol in the solution so frankly there is so far no combination I know of which can last more than 1 month in a 1.5 litre bottle. Trial and error to get the best that works for you. *just adding my two cents worth* |

hi ryzcris,
we can keep this thread always alive with all our experiment results hehe since the day i saw your formula... i have also been experimenting alot to get optimum result... smthing that will give intense bubbling and can last for a mth hehe... but it is an "ambition" at the moment... hope that hardwork can make my dram come true hehe |
