High pressure irrigation plumber here. Your issues aren't with the canister. You chose well. The issue is with the diameter of your hose and bubbler. If you have keep the depth of the bubbler that deep the pressure demand increases. I'd try raising it and also increasing diameter. Best of luck, cant wait to see new results. Thank you for sharing your experiments and results

Making mistakes is better than faking perfections! Great video Mark! Seemed like such a sound principle but I guess the way those barrels are made with that seal line down the middle has created a weak point. I used to do a lot of home brewing and would reccomend a large plastic fermenter for v2. I have a few 25litre ones gathering dust in the shed back at my mums. 👍

An option would be to use an empty beer keg, it is made to withstand great pressure. I have one at home maybe I'll try one day

The reason why simple 2L and 500mL bottle can hold pressure so well is because they actually designed to withstand up to 200 PSI when they are filled with soda from the factory. So they aren't exactly as flimsy as they seem lol

you could use 6 or 8 inch diameter PVC (sewer) pipe with a glued standard end cap on one end and a screw end cap on the other with a gasket. The cool thing is you can make it as tall as you want to make the volume you need, but a 3 foot length of 6 inch would be about 4.5 gallons, a 2 foot length of 8 inch would be about 5 gallons.

I already have a CO2 system I'm happy with but your voice and presence is just so soothing I watched anyway lol

Thank you for including failed experiments too and not giving up. Can’t wait to see how you handle things next.

Normal yeast tends to die when the alcohol reaches over 10%. Wine makers create strains that can tolerate higher but if you just add the sugar bit by bit the yeast evolves and you can make home made wine that's up to 16%.

Thank you for trying sir, really appreciate your work.!👏👏

MJ, teaching kids to make their own alcohol since before it was cool.

A brewer's demijohn could possibly work.. love to see you try that out.

Loved this video! Try this...Halfords 20L Jerry can with screw cap for fuel. 😜

Thanks for showing the failure, which everyone don't show. I had the same doubt of the containers flexibility.

Co2 gas and pressure make holes cracks in cheap plastics and tubes, you need to use something which can hold a lot of Co2 gas pressure maybe a 4" PVC pipe. But it was a good try. keep experimenting. Thank you

You were very lucky in that jerrican didn't explode or open on half... that is not safe at all or made for something to hold so much pressure. In past I've used DIY CO2 systems for bigger tanks but with normal diffusers, and to achieve 2bps we just need two tea spoons of yeast, 2 tea spoons of baking soda, 2 cups of sugar and hot water. I never have used gelatin in my mixes... To make it last longer, use a plastic water container of 6L ;-)

Thanks for the courage to experiment and share the results. Guess the plastic selection needs higher flexibility.

I've had good luck connecting 2 liter soda bottles in a series. They are built to withstand pressure, and you can change each bottle individually to keep the co2 levels more even. Using two 2L bottles was enough to make my 29 gallon tank show lime green on a drop checker. I use your sugar/gelatin recipe. I've had the best luck using wine yeast (champagne yeast has the best alcohol tolerance) and adding yeast energizer. It provides crucial nutrients to the yeast so you get a healthy fermentation. Wine and mead makers often use it. Thank you for sharing all your experiments! I learn a lot watching you.

I do it also with a 5 l canister... works like a charm

YES, SIR MJ YOUR VIDEOS ARE REASSURRING, AND PRACTICAL....BELIVE YOUR SYTEM IS LARGE AND WILL WORK, MY 2L SODA BOTTLE GAVE WAY TO PRESSURE ON MY DIY CO2 SYSTEM REPLACED OLD WITH NEW WORKS WELL NOW, EVEN MADE BUBBLE COUNTER AND CO2 CHECKER..😁

Fun experiment MJ! Hey maybe we could try one of those pressure sprayers used in gardening (without manually pumping pressure into them of course). A high quality 10L one should cost about 30 euros, so definitely more than that canister you used. But they're made to handle the pressure. Plus they come with a hose output so no need to DIY that. And some of them have a "safety valve" to release excess pressure. I'd have to go inspect one at the supermarket to see if it would work.

You still receive a big like. Keep going, very informative video and lot of study material.

Definitely like soda + citric acid better as it can be shut off during the night using a cheap shut off valve because the shutting off of the system will shunt the equilibrium pendulum between the two bottles. It is however a bit more costly.

Have you considered a yeast used for brewing like a Champagne or Mead yeast? They can tolerate higher percentages of alcohol before being killed. The downside would be they may cost a bit more per packet and they may ferment more aggresively.

the way of mix it kick start it after is what works best for me

Love the shelf with all the small aquariums, there is just so much to explore, compared to just one big tank! When i move someday, i will definitely steal that idea. For the CO2: Maybe try to find a pressure cooker with a metal lid? Would looove to see one of these next to your tank :'D

Try searching for a pressure barrel for making beer at home They should work and not be expensive

Long time ago I've seen a DIY generator made of refitted 1 gallon size manual weed sprayer. They're made of pressure withstanding plastics. It was neat, but since I'm manual task challenged, I've always only used hp cylinders. Kudos for posting those little fails. It will save some folks the hassle you experienced. 👍

Great co2 DIY 👍🏻

I think those kinds of CO2 systems do not produce enough pressure to go through the diffuser (those type with micro ceramic). So the pressure built up in your canister and it might be the reason that it broke. I had the same CO2 system with the same diffuser and it never really worked, so i changed the diffuser :) Was a nice experience to watch i'll be glad to see more!

Using a two pop bottle diy system I have seen the pressure go as high as 130 psi, I believe the pop bottle can explode around 150 psi so not surprised :) really enjoy your videos

I'm glad it didn't blast these water container aren't build to tolerate pressure best is to use soda bottle they can take up to 150 psi

Use the water gallon from mineral water

Hola de las pocas personas que muestran también cuando las cosas no funcionan, la mayoría suben videos únicamente de lo que si funciona y sale bien, saludos desde Chihuahua México

TRY USING AN OLD EMPTY CO2 FIRE EXTINGUISHER BOTTLE

I like your honesty ❤

Very informative and useful. Thanks a lot. 😁

i just bought a system that uses baking soda and citric acid. it came with a solonoid valve so i can hook it up to a timer. i haven't set it up yet and it's my first attempt at co2 so i don't have high expectations. it was a cheap system ($40) so my plan is to use it as a learning experience.

i appreciate the attempt!

Loved this video! It is always awesome to see your experiments. If you tried it again, I would recommend that you try using a metal beer keg, or something very strong like that. As always, we learn from our mistakes, and at least you learnt.

Hey mj! You should totally do what too much light does to a plant. But of course it will be hard because you have to prevent algae growth. I think too much light can stunt a plant from growing. Thanks for reading.

5 Gallon Glass bottle for wine making. Looks similar to a bottle for a water dispenser. They make rubber bung stoppers for them that may even be the right size for the airline tubing. I'd be interested in seeing how well it works if you decide to try it.

Salut mark, wahooo !!! Sacré vidéo j'ai adoré cette expérience dommage pour le bidon mais c'était sur que cela allé arrivé. Je suis boulanger et je faisait mon co2 au debut comme toi et seul les barrilles avec les clips sur le côté peuvent résister a cette pression. Et aussi faire plusieurs sortis pour alimenter d'autres bacs car le co2 a l'intérieur n'a pas assez de sorti et du coup les bidons fissures. Mais en tous cas ta vidéo était super sympa et cool. J'avais déjà fait l'expérience dans le passé mais toi en vidéo j'ai trouvé ça super rigolo. Bravo en tous cas et vivement la partie 2. Bonne soirée.

Hi like a lot experiences. Congratulations

i would think about using a weed sprayer. they're usually 2 gallons and are built to withstand pressure in the 40-60psi range before the safety valve releases . a simple hose barb going from the sprayer to your co2 line should do the trick i would think. plus a nice wide mouth for easier cleaning and loading. id really like to see you try that out

Hello Mark, to my yeast co2 bottle systems i always use just air stones, easy to adjust needs, bottles can hold up to 40 - 50 PSI or 276 -379 KPA, with diffusers attached to yeast co2 system i have difficulties to pass thru. Love your channel, keep doing what you doing :)

Loved the failed experiment! Thank you for sharing ALL your creative experiences. I have been using your recipe for 6 months now in various bottles, I had some distended bottles but no explosions trying various brands I have here in the USA between .35 and 2L. I stopped looking at the recipe, have always guessed on amounts and have always made multiple batches leading to too much gelatin. I just realized I’m not adding enough water to my bottles and that’s why my yeast is dying before the gelatin is gone. Thanks for explaining it again in a different way so I could figure out what I’m doing wrong!

Use a 5 gallon food grade bucket and lid. The same as you would to make homemade alcohol. Cheap and easy.

You could use a chemical grade plastic barrel which will be stronger which could withstand the pressure..!!

Soda bottles are designed to hold pressure. Maybe try a couple 3 liter bottles.

Hahahaha this is so funny but its sad that it had a crack but dissapointment set aside keep up the good work mark💪

The ideal fermentation container would be a glass carboy, or a PET one like for making beer or wine. The homebrew store will have a rubber bung that you can drill out to the diameter of the air hose if they don't have one with the right size hole on the shelf. Pressure in the system will be regulated by how deep you put the diffuser into the tank since pressure increases with depth.

Use large containers that allow pressurized content. Like for gasoline and other stuff..

Go for round containers. They are way stronger than square shaped ones

Try using baking soda and citric acid powder. They do sell this metal tube with needle valve, pressure gauge, drop counter, solenoid valve and more in a package for you. My 200L aquarium requires a refill every 3-4 weeks. Quite economical in my opinion. And it uses 2 soda bottles. Easy to hide.

I'm using a 15gal demijean fermentation vessel to fill a 10gal passive co² system for a 200gal aquaponics system

Try a brand new commercial gas can container, 5 gallons. Doing landscaping in the summer, if the can in the sun and hot, I've seen the can expand almost like a balloon, but never popped or leak. Only problem is they're usually a solid color, some have a thin clear strip to see water levels. Not sure if that affects the yeast with little light

A tip is to shake it or make sure it's aerated as the yeast uses oxygen to work. That's pretty important when fermenting beer, which I do a lot. Also a good idea would be to search for a second hand corny keg for beer, it's tested to 5bars and made of stainless steel.

wow that's huge 😁

Love these videos! I guess the shape of the smaller bottles are designed to hold pressure better seeing as the pressure can get pretty high in them before you even open them. Thanks for sharing!

Wow i like the way you think. . . Mad scientist hehehe anyway i appreciate your transparency and honestly. Unlike other channels that post and no follow thru. Keep up the experiments. and if at first you dont succeed try again.

Man great idea and sucks that the container couldn’t hold! Hopefully you figure out a better container bud! Cool video! I was thinking of adding dyi co2 to my 29 gallon tank!

thanks for this video maybe you failed but iearn something for this experiment and learn also so thank you.

Awwwww man! Such a shame. Mind you, the video was worth watching for the insight into yeast vs. alcohol alone. Never thought about that! Thanks 😊

The yeast is barely able to survive under anaerobic (no oxigen) conditions by fermentation. To reproduce and multiply it requires oxygen. You need to scale the dose of yeast with the volume of the container, because you are almost limited to the amount you dose in. Also, the flimsy bottle is manufactured in one piece, without seams. The canister is not and that's why it breaks. I think your best shot at scaling up yeast production is over of those 5L mineral water canisters with handle. Still, a big upgrade from a 1.5L. Keep it up, I want to see how this all ends. 😁

I think it might be the shape of the container? Like the gas in a 2 litre bottle goes to the top where the lid is, in a symmetrically, centrally located gas outflow? And maybe this helped with pushing the gas in a way that didn't warp the container. Not sure though. I'm thinking this larger project could work if a bigger bottle could be used

i love this channel😂😂😂 keep up the great content!

some soda sells 3ltr bottles here in the states. Could try finding those. Or a 5 gal bucket with lid from hardware store.

Have you ever done the yeast sugar method in the steel co 2 reactor canister?

try a "waterkluis" or "voerton" they come in relatively good sizes and can handle a bit more pressure.

You can try a beer pressure vessel from the home brewing shop - its designed for exactly this.

Sure, you’ll need bottle or container like pepsi and soda bottles that can take the pressure. I tried before using normal bottles or milk plastic containers and it exploded several times until i thought of changing it to Pepsi bottles and it has been working perfect since then; anyway its a great video really and I have been thinking the same😂 like bigger container to last more time or for a big tank 😂. Keep it up bro, best of luck 🤞❤️

Wow. Wasn't expecting this kind of pressure! I think that you were lucky that it didn't actually explode and covered your apartment in "yeast paste" :P Cool experiment though, thanks for sharing!

Thanks for the video! I were thinking if you instead make many 1.5L bottles in series with T joints. The advantages are: The bottles is not running out of co2 at the same day. If you reload one bottle WHEN light switch off then the remaining bottles will bring up the pressure until the next day when light goes on. Even if the yeast reaction have not really started in the new reloaded bottle. In short no waiting for yeast and pressure to build up and no co2 off days for the tank (only the first initial setup after that one bottle at the time). Another benefit is you can mix bottle solution some of them low and slow and some of them as high and fast. (That way you can see on the bubble counter how many "low and slow" and "high and fast" ratio of bottles you optimal need.) The drawback is that there is more joints.

Can you make a "prepare your tanks for vacation" video? I will be gone for 2 week in late May and would like some advice on this.

@MJAquascaping maybe a a food grade 5 gallon bucket with a lid similar to a 5 gallon paint bucket. They have no seams to burst and the come with a cap similar to the one on the bottle you used.

Soda plastic bottles support 7 times the atmosphere pressure before the cap fails (it's the week point). That is quite a lot but it involves safety when handling (or dropping ^^). Tanks for gazoline should be stronger (resist heat expention) or beer if it exists in large size...

Thanks for the experiment. The principle walkthrough really help, and the fact it failed doesnt matter. Actually makes me more motivated to try myself 👍 seeing that it dont blow up or anything haha. How did u go about dismantling it? Just unscrewed the top and let the pressure out gradually?

Bad luck on getting a leaky container! Small holes can be repaired by melting the sides together using a soldering iron. Would like to see you try again, thanks for posting this video. Tot siens!

U can try big bottle of water 5L, it's not 20L but it's strong bottle.

Used diy CO2 for a year or so when I was getting into fw planted tanks. Works great if you get the mix right, and now I see there are fittings available to make a Coke Bottle reactor even more efficient. But, at the end of the day, the fluctuating output levels, the hassle of mixing up a new batch every week or two, the mess...it's just so much easier and rewarding to invest in a co2 bottle and proper regulator, with a solenoid and ceramic diffuser.

My co2 recipie is: 2cups sugar and 20 grams of agar powder for the base added to 500 ml of boiling water. Then left to set in the bottle. 1 cup of sugar to 1 cup of water with 1.5 TSP of yeast which is proofed ( add 1:1 sugar and yeast to 1cup warm water and wait for 10 mins or so for bubbles). Add 1 TSP of milk and 1/3 TSP of baking soda. Pour this mix onto the jello mix. It'll take 2 to 3 hrs to start , adding sugar to the yeast mix ensures that you will get a quicker reaction with the residual yeast attacking the jello. Just change the yeast water if the jello is not fully consumed when the reaction slows down. PS: it will produce a huge amount of CO2 initially so ensure that your diffuser is higher than usual so as not to drown your fish. Don't ask me how I know.

did you check that there was flow thru the line from the cap? it seems that the container cracked because there was too much pressure, and you never got bubbles... I think the line was too tight going thru the cap, you actually pinched the line. you should redo the system and make sure the line can flow (blow air thru the line) before starting again.

The thing is that pressure works differently based on the container. Since your container has a much bigger surface area, for the same pressure, there is a lot more force on the walls of the can than for a soda bottle. Why not just use 13 soda bottles connected together haha?

Could you try adding some salt to diy co2? In bakery salt limit the active of yeast, so may it possible reduce co2 outcome?

Try using a Big mineral water or distilled water container 6-9liters will work the same as soda bottles, i already tried that type of big container, really incapablenof holding pressure for co2....

Brilliant idea, definitely need to try the gelatin mixture. Have you looked at home brew kits? They'd have a fermentation container that's designed to deal with the pressure

Salut , Tu as eu de la chance qu'il lâche par le haut !!! 😂 Pas une goutte par terre 👍 Comme bouteille de co2 , pourquoi ne part tu pas sur un extincteur !!! Il y a les détendeurs à ce pas .... l'ouvrir , le remplir et c'est parti !!! (Entonnoir) Poncé ou repeint , je trouve que c'est l'idéal , ça cassera pas ! .... et pas cher , à part le detendeur/electrovanne ! Bonne continuation à ta chaîne . 😉😎

Friend, do the same thing (with this installation - or very similar) but use citric acid and baking soda. This is when it starts 100 times faster, the pressure is higher (even up to 10 bar), it works 3X longer. A good movie I give a thumbs up.

I do 3D printing and the bottles are made of PET vs polyurethane on the larger container. It's why it feels different and didn't work.

One question? Can I use a period time CO2 and then just when my plants are ok and well I just take it out.? What's are props and cons

Those 20lit water bottles (blue ones usually) for water dispensers?

You know those cans who are used on beer dispensers the can It is made of thick aluminum And I'm talkin about The ones with beer in them And for the same reason they should be able to hold pressure and not explode

Ha ha ha. I loved the experiment. We always want more, bigger, better 🤣👍I guess you could have used the co2 reactor instead of co2 diffuser. Less pressure. Can't wait to see what you came up next.👍🤣

I think there is an issue with your diffuser, i had the same issue with smaller ones, The pressure was good but no bubbles, when i pulled out the diffuser from the tube, all the pressurized co2 came out in a second. Just make sure the diffuser is okay by giving it a blow.

Had been watching ur vedios for a long time.. Can i have a suggestion..container couldnt handle the pressure required to push co2 through the diffuser i guess.. Either change the diffuser in to something simple.. Or need to use more pressure withstanding container.😊

I was actually cringing!🤣 I remember some neighbour tried to make nettle beer in some glass bottles and got the mixture a bit wrong, they were exploding and going off like cannons. Great experiment but I would definitely suggest whatever vessel you use it must be able to pressurise. I wonder how much CO2 you could generate in say a 3 litre Cola bottle. I loved the video, thanks for sharing.

Can you use an air stone instead of co2 defuser ?

Shouldn't you have seen bubbles long before the canister ruptured ? Are you sure there wasn't a blockage somewhere ?

how much pressure do you need for the defuser? ... it looks almost as if there was far too much pressure (the plastic on those containers is a different type of plastic), gas should have been coming out of the hose surely... you could always go super extreme as well with that container and go 15l of sugar water and gelatin mix and using a 1.5l bottle as a wash bottle you'd probably need a lot of yeast... look forward to the next instalment of this experiment as I'm having to look at co2 for my planted tank to get it lusher
