DIY CO2 FROM CITRIC ACID AND BAKING SODA - COLOMBO CO2 GENERATOR

[@williamaaronhicks2198]

Just did my first refill/recharge. A few things: 1 - getting the regulator off was... challenging. I’m no slouch and it took several attempts and various grips and angles to finally make it happen. When I finally did get the regulator off, there was some crystallized residue in the threads and on the o-ring from a bit of an overflow experienced during the first charge. avoid the overflow if at all possible (see more below), and this shouldn’t be a problem. 2 - there will prob be crystals when you empty the solution that’s contained inside the cylinder, which I believe to be unreacted sodium bicarbonate precipitated out of solution - harmless, but be sure to get them out. 3 - rinse the cylinder out with *very* hot water, then fill to top up to the threads with more hot water. Let sit for a few moments until cylinder is too hot to handle, then empty. leave upright to cool and the residual heat in the metal helps to dry the cylinder inside, which helps minimize bicarb or citric acid sticking to threads during refill. 4 - remove the o-ring from the regulator and rinse - but don’t forget to put it back on the regulator after. *carefully* rinse the threads of the regulator (as needed), being careful not to get water inside the regulator itself - do *not* immerse the regulator or turn it upside down under running water such that water could possibly get inside the regulator body itself. sit upright on a piece of kitchen paper or a towel to dry, allowing threads sufficient time to dry completely before reinstalling 5 - when you add the recharge chemicals, add citric acid first. it is lighter/less dense and dissolves more quickly in water. adding the bicarb second and on top of the citric acid provides a “barrier” to a premature reaction, as it is more dense and dissolves more slowly in water. gently shake cylinder after each addition of the two components to spread powders into even layers, helping to facilitate this insulating effect. 6 - the ~45° cylinder tilt recommendation while adding water is really effective, especially after the above layering technique. while pouring the water slowly and steadily at this angle, I heard the first bit of the reaction begin from inside the cylinder, but it never bubbled over and I was able to reinstall/rethread the regulator with *zero* overflow or spill, which hopefully means no stuck threads next time I recharge. instinctually it may seem better to pour the water into the cylinder as quickly as possible, but doing so will invariably stir up the chemical layers leading to a potentially very messy and unexpected premature reactulation - however do not be embarrassed if it happens to you, as it is a common occurrence during one’s first time. (...you’re welcome 😜) 7 - once the regulator is fully reinstalled and the cylinder is properly sealed, gently swirl - do *not* shake - the cylinder contents/solution to help facilitate proper mixing and a complete reaction. After above, my cylinder was fully recharged and ready to go within about an hour, but will continue to react over the next several hours. Overall I’m really pleased with how the system has worked thus far. I’ve found several retailers with different versions of the same product for as little as US $80, a bit more for those that include the electric solenoid. As I live in NYC and finding a CO2 provider nearby was neither convenient let alone cost effective, and I find this system to be both. And as it uses food safe ingredients to generate the reaction, there shouldn’t be any risk of introducing potentially unsafe trace elements/chemicals into the tank using CO2 from a potentially unreliable source. 👍

That is awesome! Thanks a lot for the detailed explanation 😊

[@williamaaronhicks2198]

@@aznsushi41 funny you should ask - mine ran out just about a week ago, and because of travel, I only just recharged mine today. I run a pretty low dose though, so mine probably ran way longer than Mark’s. That said, when I opened it up to do so, the threads were not gunked up like the first time I did a recharge. 🙂👍

Been seeing these a lot lately on online shops. Might switch to one sooner.

[@ElHipokondriako]

This is by far the most expensive way you could ever conceive to generate CO2. Allow me to run some numbers: 1. The stoichiometry bicarbonate:citric is 3:1 (in moles, not in grams) 2. I believe the citric acid sold as food grade, even when advertised as pure, is monohydrate, at least partially. 1 mol of sodium bicarbonate is 84g and reacts with 1/3 mol of citric acid, 192/3 = 64g if anhydrous, 210/3 = 70g if monohydrate. The reaction results in 1 mol of CO2, 44g. To sum up, you mix 84g of bicarbonate with 64g to 70g of citric acid to obtain 44g of CO2. You can read in the instructions to add 200g, 200g, and 300mL of water. While there is a slight excess of bicarbonate, I think it's better that way because bicarbonate is way cheaper that citric acid. Following the instructions you will get between 200/64*44=137.5g and 210/70*44=125g of CO2. Colombo claims on their product description 105g of CO2 per batch, which seems about right considering part of the CO2 is lost on preparation and remaining gas at the end. 105g of CO2 per 6$ seems cheap, but it's actually 60$ per kg. I can find CO2 refills online of 3.15Kg for 30£ (about 33$). That's about 1£ per 100g! With citric acid method you are paying 6 times the money for CO2 after expending 200£ (or 220$) in an overpriced metal canister. The maths just don't add up. You need to lower the price of a refill to 1$ just to break even. That's about 3$ per kg of citric acid and 2$ per kg of bicarbonate. I insist, just to break even! Unless they find a very good deal on citric, DIYers should stick to the sugar method. Sugar fermentation (anaerobic) yields 2 mols of CO2 (88g) per mol of glucose (180g). That is 488g of CO2 per kg of sugar. If 1Kg of sugar is about 1$, yeast CO2 is roughly 2.20$ per Kg. Even if you account that 2/3 of CO2 are lost during the night, you are still on 6.60$ per Kg (compared to 10$ pressurised and 60$ by citric acid). TL;DR Sugar-yeast is the best DIY method. It's uncomfortable, stinky, low pressure, but it's C H E A P. If you are going to spend 200$ get a professional system. Stay away from citric acid unless you can get it for 3$ per Kg or less.

Hi.. oh wow MJ, great minds think alike, I am literally going to put out a review and setup of this co2 system on my channel tomorrow. Nice video MJ as always

[@MJAquascaping]

hahaha awesome! Ill definitely be checking out your review!

[@tjablaj]

I would recommend to go with a 1:3 raio for the acid and soda as this is how the reactionequation looks like: 3NaHCO3 + C6H8O7 → C6H5Na3O7 + 3CO2 + 3H2O. NaHCO3 is sodium bicarbonate, C6H8O7 is citric acid. When they react the produce C6H5Na3O7 (sodium citrate, a salt), CO2 and H2O. To get best reaction this is inportant as if you go 1:1 ratio you wont get as much CO2 out of it.

[@paulandrewgomez861]

Niklas, what is the best ratio to get maximum Co2 per batch? What is it in grams? Solvent is 100ml tap water. Thanks!

[@paulandrewgomez861]

Does the solvent (volume of water) matter? I was reading only 7.8g of Baking soda can fully dissolve in 100ml H2O.

[@tjablaj]

@@paulandrewgomez861 1:3 ratio. 1 part citric acid and 3 parts sodium bicarbonate. About the water you dont really need much, since the reaction itself will create water. You just need a splash to start the reaction.

[@paulandrewgomez861]

@@tjablaj omg, you are amazing! Thanks for the reply. I'm still in google looking for answers. 😆 lol!

[@paulandrewgomez861]

@@tjablaj It's confusing. I had just read this: "So to maximize the yield of CO2 gas (since this is the gas produced and I imagine you are interested in the dramatics!) you should use one mole of citric acid and three moles of baking soda. These mole numbers can be converted to mass using molecular weights. For baking soda its 84 g/mole and for citric acid its 192 g/mol (roughly). So the ratio you want to use is 3:1 or 252/192 = 1.31. That is for every 1 gram of citric acid use 1.3 g of baking soda. This will give you the maximum amount of CO2." What is your take on this? The difference in terms of grams is huge. 1:3 is 100g Citric to 300g Baking soda. While the other source says 100g Citric to 130g Baking soda.

i watched one other video with the same setup from "aquarium shed" which was very interesting. some nerd did the math and calculated that 200g of Baking Soda and 200g of citrid acid produces 105g of Co2 (i hope this is true) lets say i buy 5kg of each substance for 20Euro each (=40 Euro in total) i can refill 25 times (5000g/200) in total 5000g baking soda plus 5000g produce 2625 g of co2. so thats 40euro for 2,6 kg co2 i would buy one under 100EUR maybe but for 200EUR i could just buy a pressurized system which is cheaper in the long run and does not need much maintenance. or am i missing something?

[@MJAquascaping]

Personally i havent tried this one, but I have tried the 2 bottle type, ive even tried just putting it in one bottle and regulating the pressure, and ive tried the sugar yeast approach, personally i havent been happy with any of them, the best reaction I've had lasted 5 days, but it was unstable, I had to constantly adjust the pressure being released everytime and im not talking daily tweaks, I'm talking multiple tweaks a day, and to top it off black beard algae loves unstable co2. To be honest if you're home all day and willing to put in the effort its probably worth it, but if you want to just set up and let it run with minimal tweaking just spend the money and get set up with a pressurised system! To me my time is worth more than DIY co2, and I'll spend the money to keep my time!

The cheapest CO2 is sodastream, which you can buy from groceries or supermarket. The only problem is that the sodastream bottle doesn’t fit into aquarium CO2 pressure regulator. So you need to buy an adaptor to connect the two, and you will have pure and long lasting CO2 supply. This is probably the cheapest pressurised CO2 you can get from the market.

[@MJAquascaping]

Yeah I've seen a few people using sodastream. might have to try that in the future as well

[@ravemind8433]

Long term, SodaStream will be expensive. The refills are not cheap compared to filling a large tank. But it is convenient.

Hi MJ. How much pressure do you get from this co2 system?

[@jomilsison9873]

Is this safe to use for carbonating drinks?

[@daltonrobbins8189]

I’m using fire extinguishers for same thing

[@esuohelyk]

great overview of the product! I like that grey long sleeve... where's it from? 🧐

[@MJAquascaping]

Thank you! Got the long sleeve from Zara 😀

Mooi ding, alleen prijs is niet zo mooi.. 200 euro! Helaas.. MJ zou je een follow-up video kunnen maken van de high end DIY CO2 over een tijdje? Thnx alvast, goede video zoals altijd!

[@MJAquascaping]

Ik maak een follow-up zodra het eerste recept uitgewerkt is!

[@TheAgilitynut]

Ik heb dezelfde soort reactor gevonden op Amazon van een ander merk voor 69 euro. Stuk leuker.

[@mikeklein6620]

How long does one refill Last? Thanks

[@MJAquascaping]

For me almost 5 months on a small nano tank

How high does your pressure get? I set mine up yesterday and the needle is almost past the green zone after about 24 hours. Also, is it normal for water to be in the diffuser?

[@kiwiasian]

Mine never went above middle of green and last couple of weeks is in the yellow but bubble count is staying steady so I haven’t changed it. Water will get sucked from the tank into the diffuser and even up the hose when the system is off, that’s normal and isn’t a problem with a check valve installed.
