    excuse my English

    I bought a kit at home to Co2.
    Use citric acid + sodium bicarbonate, when mixed react and produce Co2.
    With this system you can get more pressure and is stable in its production.

    Can achieve high pressures necessary to use 1.8 bar CO2 atomizers.
    Hope you like

    I'm testing for spray work, we need a lot of pressure, the mixture is used almost only for this.
    I'm hoping some glass diffusers for further testing
    This is the official product page

    Another method in case you guys not aware, simple sugar and yeast (for making bread) mixture can produce co2 too.

    Tried yeast and sugar method before, it did not work that well for me.

    This mixture is used but not stable in its production.
    Is a biological reaction depends on the reproduction of the bacteria of yeast.
    It takes a while to start production, has great production the first few days and then goes into a decline.

    This chemical reaction is, in 5min this list and remains constant until the reactants are depleted.

    I do not sell the product just seems odd to me to comment.
    I use pressurized co2, so I have months of tranquility

    Bro, you only used yeast an sugar?
    I failed too before, read up after that found many people try mixtures. Some use baking soda to stabilize the yeast... I tried the jello recipe with good results on low bps.

    TS also just doing experiment and sharing.

    Nope... i used yeast with baking soda and sugar. It did not really work that well for me. No problem, i understand TS is sharing too. cheers

    Re: DIY CO2 System Aquarium Plant Kit CO2 Diffuser Generator

    i wonder if rice can be used with yeast .. I mean cooked rice .. currently i am using yeast with sugar .. tried but the pressure is not huge enough .. end up have to connect the mixture to the diffuser straight .. to produce minimal CO2

    Check your bottle, home systems fail by leakage
    That type of diffuser is using?

    Re: DIY CO2 System Aquarium Plant Kit CO2 Diffuser Generator

    I have been exclusively using sugar and yeast and baking soda for a long long time for my main tank.
    I use a super-size 3L plastic coke bottle. Took half a day to startup to get stable but last >2 weeks at 1 bps. I connect it to a spring-loaded one-way check valve and feed into a reactor. The spring-loaded one way valve allow some back pressure and give a very stable CO2 bubbling.
    I still have the empty pressurized cylinder lying around, too lazy to send for top up.
    DIY top up at home (3 cups sugar, 1 tsp baking soda, 1/2 tsp yeast, fill with tap water) take only 10min. Do it at night the next day it already start bubbling.
    The baking soda is to stablize the PH of the yeast culture and limit the yeast growth to a steady rate. The amount of yeast determine the bubbling rate. I find 1/2 tsp yeast is the best (produce ~1 bps) and last the longest.



    If your DIY not successful 99% is due to the leakage at the cap connecting to the air tube.

    Re: DIY CO2 System Aquarium Plant Kit CO2 Diffuser Generator

    I am planning to buy the D301 model of this, I think it is an upgrade of what you have. Anyway, I'm really happy that someone in the hobby did actually use this.

    How is it doing so far?

    How long did one solution last?

    Thanks

    If the new model is now available.
    I bought it just as curious as I use pressurized CO2 cylinder
    Other partners are using and it has made ​​some themselves

    Re: DIY CO2 System Aquarium Plant Kit CO2 Diffuser Generator

    Thanks a lot for the reply.

    I just went ahead and order a set of the new model.

    It seems that is the next best thing to a pressurized system, not sure yet.

    I will try to document, how it works when it arrives.

    Nice Tanks by the way.

    Re: DIY CO2 System Aquarium Plant Kit CO2 Diffuser Generator

    I'm worried about the stability of the CO2 production, and the pressure build up inside the bottle.

    Can someone explain to me how is this system more stable in production compared to yeast systems?

    I find this very interesting and would like to use it for my tank as well!

    Re: DIY CO2 System Aquarium Plant Kit CO2 Diffuser Generator

    I am not really sure if I am the right person to answer your inquiry. I will try to shed light on this system the best way possible. I did watch the video both from this site and to the manufacturer's site many times. Unfortunately, the video from the manufacturer's site is in Chinese. You are from Singapore maybe you can understand what the guy from the video is saying.

    This is how I understand the process:

    When acetic acid or vinegar is mixed with baking soda, it really gives a burst of CO2 in a very short time. I have seen some videos of this on some sites (I myself tried it in small amount), although the purpose is for planted green houses, to supplement the CO2 of their outdoor plants. No problem for their purpose. They just close the greenhouse and mix acetic acid and baking soda at a considerable amount and just let it circulate inside the the greenhouse. So I had this thought, if I could only capture the released CO2 in a container and release it slowly in a planted tank, it would be the best DIY CO2 setup for a planted tank.

    To make the long story short, I search the net and found a gadget that is being sold on the net that uses acetic acid and baking soda as a component. I got so interested, and started to search for reviews about the gadget and this is when I found the only site that has one.

    Going back to the gadget specific. As seen in the video there are two containers both of which are 2 liters. The first one contain acetic acid or vinegar and the second one is the baking soda mix. In order for these two component to produce CO2 they need to mix together, this is done thru the tube connecting the two bottles. By releasing the needle valve the two component mix, when the needle valve is release gas is release in the environment coming from bottle B in effect letting the acetic acid from bottle A to siphon to bottle b, does mixing the two component and producing CO2. This process is done until the pressure gauge reads 1.4 or 1.5 Kg/cubic cm. Then the release valve is lock and no mixing of acetic acid and baking soda is possible so no production of CO2 but then you have enough CO2 in the bottle for you to release in in your tank. As you consume the CO2 in the bottle the pressure gauge reads lower and slowly acetic acid from bottle A slowly transfer to bottle B the baking soda, so increasing CO2 again as the CO2 builds up the transfer from the two bottle stops again. Thus, producing a continues source of CO2 until the components are gone.

    So, this is how I understand the system thru the video. I hope you will watch the manufacturer's video and also shed light on this gadget. Maybe you will understand it more, if you understand Chinese. Anyway, I am waiting for my order to arrive. And give more info once it is here and it put into use. Hope I did help somehow.

    It seems, that there will be no problem with pressure build-up. I think what will be more of a problem is how long will it last. I hope it last for a reasonable time before mixing another set again.
