As a craft beer brewer I can shed a little light on making yeast last longer and co2 more voluminous. Most of the DIY planted tank systems I see use way too much sugar. If using baking yeast, 1 cup of sugar to 8 cups of water is too much. Baking yeast dies at about 4% alcohol. If using brewers yeast ( available from local or on line home brew sources), then you can use 3 times more sugar to water. Also, dosing a new batch of sugar water with reclaimed yeast will work well for 5 or 8 generations of use. Also using a prepared yeast nutrient which contains diamonium sulfide ( also available from home brew supply) will make yeast last much longer in a nutrient poor solution of table sugar. An addition of a small amount of fruit juice will substitute in a reasonable manner as a substitute for commercial yeast nutrient. Grape juice is especialy fermentable, as are palm dates.
For those asking about check valves, yes you need to have one. If you don't what happens is that once the CO2 stops producing, you'll end up getting a syphon back to your bottles, meaning water will be pulled out of your tank, the check valve stops this from happening. You should always use check valves even with regular air pumps, otherwise you risk water syphoning down and into your air pump, possible electricution or water damage to the pump. Great vid Joey
I hope you realize what a gift you are to us ?! i just found these and really im a new *addict* to aquariums and i was starting to see a strained look on my husband's face at the expenses. Im not afraid to experiment, try these, fail, get better and try again with your guidance here :) so THANK YOU really really special what your able to show us.
Dear joey, I have made myself a filter and a bodem cleaner that you have shown on your video's. I'll thank you for that. That bodem cleaner works perfectly!! Thnx!!
Joey, great vid by the way... One improvement to the system might be is joining the two pipes coming from bottle 1 and 2. By doing this you can add some water to the third bottle and then submerge the pipe coming from the two bottles so that you can create a bubble counter...
This was really helpful. I have a 50 litre tank and wanted to plant it but was a bit concerned about the cost of buying all the stuff I need. I'm glad to know that I can just grab a few bits and pieces out of the cupboard and rig something up. Thanks a lot!
nice vid. i still can't believe how well diy co2 works in my planted nano tank. it took about 3 weeks before it really started to kick in, now they won't stop growing.
I must have missed how often you need to change the mixture or add more mixture to it. I'm also not really seeing if anyone else has actually done this build with success. I truly appreciate the video and the hard work that is put into helping us learn these techniques.
i just wanted to thank you for all that you do, you've saved me hundreds of dollars throughout the last year or so since i discovered your videos, just saying, i appreciate it.
Nice video! I think Im going to try this out my self. I want to add something though! I think might work well with this system. If you want your yeast to produce moor CO2 you need to let the yeast have some supply of air from time to time. This leads to arobic respiration witch makes the yeast abel to break down the sugar moor completly. To fix this you could install a check valve from an old bike wheel tube, onto the CO2 generator. Then u can use a bike air pump to pump air into the system. And also the pump would counter the pressure difference in and outside the system so the air actualy can enter through the check valve even thought there is higher pressure inside the system then outside.
Joey, thanks for *all* your videos, Few things in regards to this video: - Cut the tube at a 45deg angle: it's much easier to plug in the cap. - Use soda bottles as they are made to resist internal pressure. - In your mix add 1-2 small pinch of salt: it slightly inhibits the growth of yeast and prevents a production spike. (last longer) Also add 1 or 2 drops of vinegar to the water to bring down the PH. Add few cubes of super sweetened jell-o: it dissolve very slowly and release sugar.
Thicker bottles always help for the exploding thing. And when you say airstones are expensive in your country, do you mean an air pump or the actual airstone piece? Because you can still get an air pump to bubble with some tubing and no airstone, the airstone is just easier and looks nice.
Hey Joey, Lobe your videos. I am currently researching different tank set ups and such to do a complete rebuild on my 55gal freshwater tank. I would like to add an overflow into a ten gal sump that also has its own overflow build out of spare air line. The duel tank duel overflow combined with a drip system should eliminate water changes while adding additional filtration and auto-top-off. I built a single bottle of the generator as a proof on concept. Keep the vids coming.
I have been doing DIY Co2 this way but I use a TINY fountain pump (or beta tank power head pump) and I put a barb (from a drip system emitter I broke apart since it is the same size tubing and then has the big round end) through the little grate where the pump sucks in water. Then route the Co2 hose to that and tilt the pump a little so it sucks water and gas. The power head diffuses the gas beautifully, creates circulation of the gas AND, the best part is it acts like a solenoid
Thanks for all the DIY info Joey, I've been watching your channel for a while and I appreciate all the awesome free info you're giving out. I recently ran into an issue on a smaller 20gal sectional planted tank" 1 filter 2 tanks" where I upgraded the lighting too fast and went waaay too high and black beard ate my tanks up lol. Increasing co2 was the way to go not only for killing the algae but for plant growth. I previously tried chemical co2 generators which were around $20 a month and with this system you definitely just saved me money so I just wanted to say thank you for a quick and ez nano tank co2 generator for my shrimp tanks!
Nice Vid. I also found that plastic airline connectors inserted into the holes in the bottle cap also form their own seal without the need for glue of any kind.
Very clever and informative, thanks for sharing. Also, I've been wondering how to create CO2 and forgot that bread yeas and sugar does this. Thanks for the reminder. This method is also useful for someone who is trying to create a bed bug trap which uses chemical CO2. Using bread yeast for CO2 creation is excellent.
This video is great, many thanks - so helpful, starting a new aquarium and this is saving me a lot of money and also helped me understand the whole CO2 deal ! Keep it up!
Great video! I will definitely use your method when I decide to try out CO2. I just wanted to point out that those plant species you chose don't even need CO2 injection, unless you wanted to try growing them at a more rapid rate.
Thanks for your video, it was really informative. I have another suggestion for a diy diffuser, you can use small bamboo skewers (or toothpicks) and stick it into the tube. Then cut the skewer such that only a bit of it is sticking out. The air will diffuse through the skewers in really small bubbles. You will also have to block off the end of the tube. You can run the tubing across the bottom of the tank and stick the skewers into the parts of the tube that will be closer to the plants.
Looks fine, but from what I remember, silicone tubes that comes from the power mixture (yeast mixture), should be extended in order to reach below the water in the third tank. The water in that tank should purify the gas, that is formed by fermentation. The rest is as much as possible in line with practice. Besides i use a 1410 recepture, that means 1l of hot water, 400dg of sugar and 10dg of yeast.
Dude, this is probably the best explained diy co2 video I've watched. I just had two (probably dumb) questions: would the blue and white filter media work in place of the sponge on the diffuser? and since I don't want to have to run an airstone at night, would it be ok to just take the cap off the water bottles at night, or would the pressure be lost?
Hi Joey, Do you still have this tank set up? If so would you post a new video of it as it is today. I'd like to see how it has done from then to now. Thanks and I enjoy all of your DIY videos. I am also a member of DIYfishkeepers.
i brew beer ...could i use a 180 to 200 gallon tank for aquascaping, just rig my carboy up to a dyi filter and diffuser... combining hobbies has me stoked... how would this work? any problems come to mind?
Yeah, you're right. I think he should clarify that the hose into the third bottle needs to go under water. It seems that he didn't sank the hose in the third bottle. Which is extremely important because you need to get rid of the other gases and alcohols produced by the reaction. But the bottle is there, there is no need for an extra bottle ;-)
If anyone is using a HOB filter for their planted tank, a great idea is to use a suction cup to secure the CO2 tube opening right above the impeller, that way the bubbles get pulled into the impeller and chopped up.
hey joey nice to have those staff you have shown. please if you can give a idea of preparing soil for tank of 36 inch long by 18 inch in width and height i will be very much thankful to you bro..
I don't know if this has already been asked, I'm just setting my unit up now, does the amount of CO2 produced depend on room temperature? Will the reaction produce more CO2 when warmer? the room my tank is in is fairly cool especially now we're going into winter so do i need to find a way of keeping the mixture warmer to produce the required level of CO2? This is an awesome vid and from all the ones I ended up watching (which was a lot) this was by far the best and easiest to follow, thanks :)
The great thing about yeast is when it runs out of food it doesn't die, it goes dormant. If you continually run CO2 using residual yeast from the last run will 'restart' when sugar is added again so adding new yeast is not required!
You are amazing!!! I love your videos, they are so helpfull, eventhough I'm not making most the things you show, it really helps for later projects... thanks.... :D
I never saw a 3 bottle method before. I did this many years ago with a single 2 liter bottle on a 55 gallon community tank and never had any issues with fish dieing. Added a little baking soda to the mix to slow the reaction down some. To diffuse I used an airstone, but also tried running the CO2 tube to the filter intake of a canister filter- once with one filled with media with no issues and then added an additional smaller empty canister filter with no issue.
The video mentioned using an inline valve to regulate the flow of CO2, That would also enable you to easily shut it off at night. . Another idea I found works well: If you have an internal filter, drill another hole just above the inlet slots & feed the airline into it. The impeller will chop up the CO2 bubbles way finer than any diffuser.
What do you think of adding a T-valve with another check valve leading to the open air? That way you add CO2 and well as O2, hopefully resulting in less asphyxiated fish. It works in my head but I don't know if it really works.
Air-stone is basically a diffuser. You need a specific diffuser for CO2 because air-stones do not release small enough bubbles to be taken into into the water by the time they reach the surface and escape.
can you do a guide on how to build a planted aquarium. what things should i do first? etc.. etc.. I'm still confuse on how to start and what to consider first. thank you
Be that as it may, it's never stopped planted aquariums (nor my own for that matter) from growing well over the years. I'm sure you'd increase the growth rate. But NEEDED? Not in my experience. The only possible scenario were it really would be needed is when attempting to grow some really dense or harder to grow plants ala the Iwagumi tanks. But vals, anubias etc etc.not necessary. By the way, I like how you actually take the time to respond to commentators. Props to you my good sir :)
Hey Joey, as always great information. I do have a few questions though. 1. could you just attach an small air stone to the line instead of building the Co2 diffuser? 2. Can you also attach the Co2 line to an air pump line and have both flow into the tank at once?
Hello Joey!I liked your video and I just finished the setup.I have a dilemma/question : as a diffuser,can I use the one from an old Tetra CO2 Optimat(maybe you know it,if not,Google knows it for sure :) ).This is a dilemma for me because the top of that diffuser has a very thin membrane that keeps the CO2 inside for a long period of time and the mixture with yeast and sugar produces CO2 continuously,so I am not sure if it will not accumulate too much pressure inside that big "green tube". Thanks
hey mate, great videos btw, one question, how in the world can you make the water look so clear and blueish, could you please respond or make a video about it? thank you
Thank you for all yours ideas about aquariums systems. Then i DIY me CO2, its a littlebit difficult to put the air hose through that 4,5 mm hole. I use me scissors to cut about 60 degree off the end of hose, after that its easy to put it through.
Try it without a check valve. If it still isn't making any bubbles then something went wrong with your mixture. If it does start making bubbles without your check valve on, then you will need to get a new one or you can put your bottles above the height of your aquarium, that way even without the check valve water won't siphon out of your tank.
hai joey, i have made my diy co2 coming with a diy diffuser. but the problem is the diffused co2 was too little..how can i solve it? please advice. thank you.
Hello there! Big fan of u sir! Just a bit confused here.. Is that 1cup of water + 1cup of sugar + yeast on it is to be diluted to a liter of water? Or do i need to make 4cups (250ml) of the mixture to have 1liter? And is that (tsp) a teaspoon? Not table spoon? Thig might sound ridiculous , but jyst wanted some clarification :) thank you! More power!
hey joey another informative video, I followed your design except used a 2L and then the smaller bottle for my tank but i connected the last hosing with the check valve to my tank to a old powerhead as the diffuser. Specifically i connected it to the venturi/airline valve on the output. Is this okay? I glued my bottles inside and out and i do see bubbles, the powerhead is on too, is this a good idea?.
Couldn't you attach a solenoid valve controlled by a timer? Although, now that I say it I guess the gas would build up in the bottle over night... I wonder if you had a larger gas/liquid separating bottle if it would even be an issue.
when attaching the airline to the lids of the bottles you can also drill just a bit bigger hole, put the tubing through the hole and then lightly heat up the end of the tubing with a heat gun, torch or lighter, then flare it out a lot with a sharpie or some type of pen. Then pull it snug. and its airtight
Joey! You are not the king of DIY... You are THE GOD OF DIY. I've been looking for something like this to my tank, but i'm a little bit worried about killing my fish and the exploding gas bottles. Any way of making sure that i'm not going to kill them or make the bottles explode?. I read something you said about an airstone, but that is VERY expensive here in my country and it's very hard to find, anything else i can use?. PD: Sorry for my English :)
Joey, have you ever tried another source of CO2? I think that yeast will not deliver enough pressure. I'm thinking about mixing citric acid with sodium bicarbonate. Will share with my results. pH can be a problem. Thank you for your video.
Ok, I made mine tonight, I did not like the unsightly plastic bottle in the tank so I used Fluval Bio-Foam cut a hole in it then I inserted the end of the hose that has a bubble stone on it in to the foam. I then put the foam in to a alagator sskull decoration so it is out of sight. The decoration is under the filter flow, so I hope it assists in stiring up the co2 bubbles.I will report on it later.
As a craft beer brewer I can shed a little light on making yeast last longer and co2 more voluminous. Most of the DIY planted tank systems I see use way too much sugar. If using baking yeast, 1 cup of sugar to 8 cups of water is too much. Baking yeast dies at about 4% alcohol.

An addition of a small amount of fruit juice will substitute in a reasonable manner as a substitute for commercial yeast nutrient. Grape juice is especialy fermentable, as are palm dates.
Brewers yeast is cheaper too. Now to find a way of connecting the demi-john airlock to tank, as I already make wine :D
I used some waterproof glue to attach an aquarium air hose to the hole in the center of the stopper.
Managed it with silicone sealer and put a bottle in between just in case:D
I will scour youtube for more of your wise words
What i like about you is, a normal person will take this vid and make it 5 mins but you take your time to explain

If you don't what happens is that once the CO2 stops producing, you'll end up getting a syphon back to your bottles, meaning water will be pulled out of your tank, the check valve stops this from happening.

Best how to video I have seen plan to make this system for my 29 gal tank
This is very impressive and I have subbed. You saved me about a hundred bucks! It's really expensive to buy co2 systems where I live.

i use regular 2 liter diy co2 system but this looks good so ill try it on a 10 see how goes. good work and luv your helpful vids, keep it up
I use a 1 liter bottle and tape the smaller bottom with it so it becomes one unit.
Thanks for all the DIY info Joey, I've been watching your channel for a while and I appreciate all the awesome free info you're giving out.

Keep it up!
Awesome! That's the cleanest DIY CO2 setup I've seen on RUclips. Thanks! I will be running this on my new planted tank!
jaysonmetsfan hey plz reply . Does it work?
The ckeck valve can be called a non return valve which is a litte more self explanitory. I enjoy your vidios. Thank you.
Great video! I will definitely use your method when I decide to try out CO2. I just wanted to point out that those plant species you chose don't even need CO2 injection, unless you wanted to try growing them at a more rapid rate.
I've just put a variant of this together after watching your video, looking forward to seeing how it goes!
U got a amazing transformation man
Joey, if you keep the Yeast alive the check valve isn't needed, just plug the end and perforate the tube.
Thanks for your video, it was really informative.
I have another suggestion for a diy diffuser, you can use small bamboo skewers (or toothpicks) and stick it into the tube. Then cut the skewer such that only a bit of it is sticking out. The air will diffuse through the skewers in really small bubbles. You will also have to block off the end of the tube. You can run the tubing across the bottom of the tank and stick the skewers into the parts of the tube that will be closer to the plants.

Nice vid! Would love to see the diffusor in action up close.
Can't wait to give this a try with my Gatorade bottles laying around. This looks really cool.
Thanks. I really like your diffuser!
built it today waiting to see what happens as plant looks a bit depleted but hoping it will work nicely and put some life in to the plants cheers
HE JUST HIT 1m viEWS WHOOOOOOOOOOOOOP WHOOP GOOD JOB JOEY. BEEN STREAMING THIS WELL AND NOW YOU HIT IT. BOOM! KWEIL OUT
Hi Joey, Do you still have this tank set up? If so would you post a new video of it as it is today. I'd like to see how it has done from then to now. Thanks and I enjoy all of your DIY videos. I am also a member of DIYfishkeepers.
Excellent video and great tips, now to make some changes to my set up, love the diffuser, thanks.
i brew beer ...could i use a 180 to 200 gallon tank for aquascaping, just rig my carboy up to a dyi filter and diffuser... combining hobbies has me stoked... how would this work? any problems come to mind?
RUclips should create a "TWO-THUMBS-UP" button especially for you! Great work man and thanx for the effort.
Great video. Maybe you can make a video on how to make a pressurized paintball CO2 system?
Nice job very informational I'm going to use this method I'm going to start to grow plants for guppy/endler breeding nice job! :)
Back when Joey had a moustache. Bring it back in 2019 Joey cmon man 😂
You mean 2020
Built it the other day...works awesome! thanks bro
Your videos are so incredibly helpful and informative. Thank you for doing this. Subbed.
Yeah, you're right. I think he should clarify that the hose into the third bottle needs to go under water.

hey joey nice to have those staff you have shown. please if you can give a idea of preparing soil for tank of 36 inch long by 18 inch in width and height i will be very much thankful to you bro..
Great vid Joey
Also, to help keep costs low, there are usually coupons that can be found every month that can be used when buying sugar.
I don't know if this has already been asked, I'm just setting my unit up now, does the amount of CO2 produced depend on room temperature?

good video... my concern is about the alcohol byproduct of this process.. will that affect the fish and or tank health?
if you have the right amount of fish to make co2 yea it will work but plants my grow a bit slower
THANK YOU for explaining this thoroughly.
It works great I used a small air stone
Hey Joey, as always great information. I do have a few questions though. 1. could you just attach an small air stone to the line instead of building the Co2 diffuser? 2. Can you also attach the Co2 line to an air pump line and have both flow into the tank at once?
Man, i love this guy. Keep up all the good work :)
Hello, DIY master, i just wondering, if a airstone would work, instead using a sponge to release the co2 at the end.
Hello Joey!I liked your video and I just finished the setup.I have a dilemma/question : as a diffuser,can I use the one from an old Tetra CO2 Optimat(maybe you know it,if not,Google knows it for sure :) ).This is a dilemma for me because the top of that diffuser has a very thin membrane that keeps the CO2 inside for a long period of time and the mixture with yeast and sugar produces CO2 continuously,so I am not sure if it will not accumulate too much pressure inside that big "green tube".

great video. What is your suggestion for (my) 130 gallon tank? I don't have any live plants right now ,but I am thinking about it.
every thing works fine ..! will the plants grow like the one the shopkeeper has.....and plz tell me how to make a nice diffuser...plz!!!
hey mate, great videos btw, one question, how in the world can you make the water look so clear and blueish, could you please respond or make a video about it? thank you
Thank you for all yours ideas about aquariums systems.
Then i DIY me CO2, its a littlebit difficult to put the air hose through that 4,5 mm hole.
I use me scissors to cut about 60 degree off the end of hose, after that its easy to put it through.
this video is like giving me a great gift!
Try it without a check valve. If it still isn't making any bubbles then something went wrong with your mixture. If it does start making bubbles without your check valve on, then you will need to get a new one or you can put your bottles above the height of your aquarium, that way even without the check valve water won't siphon out of your tank.
Thank you for this video my question is why else would you need a check valve for this
hai joey, i have made my diy co2 coming with a diy diffuser. but the problem is the diffused co2 was too little..how can i solve it? please advice. thank you.
Hello there! Big fan of u sir! Just a bit confused here..
Is that 1cup of water + 1cup of sugar + yeast on it is to be diluted to a liter of water? Or do i need to make 4cups (250ml) of the mixture to have 1liter?
And is that (tsp) a teaspoon? Not table spoon?
Thig might sound ridiculous , but jyst wanted some clarification :) thank you! More power!
hey joey another informative video, I followed your design except used a 2L and then the smaller bottle for my tank but i connected the last hosing with the check valve to my tank to a old powerhead as the diffuser. Specifically i connected it to the venturi/airline valve on the output. Is this okay? I glued my bottles inside and out and i do see bubbles, the powerhead is on too, is this a good idea?.
Couldn't you attach a solenoid valve controlled by a timer? Although, now that I say it I guess the gas would build up in the bottle over night... I wonder if you had a larger gas/liquid separating bottle if it would even be an issue.
when attaching the airline to the lids of the bottles you can also drill just a bit bigger hole, put the tubing through the hole and then lightly heat up the end of the tubing with a heat gun, torch or lighter, then flare it out a lot with a sharpie or some type of pen. Then pull it snug. and its airtight
Joey! You are not the king of DIY... You are THE GOD OF DIY. I've been looking for something like this to my tank, but i'm a little bit worried about killing my fish and the exploding gas bottles. Any way of making sure that i'm not going to kill them or make the bottles explode?. I read something you said about an airstone, but that is VERY expensive here in my country and it's very hard to find, anything else i can use?.
PD: Sorry for my English :)
Joey, have you ever tried another source of CO2? I think that yeast will not deliver enough pressure. I'm thinking about mixing citric acid with sodium bicarbonate. Will share with my results. pH can be a problem. Thank you for your video.
Hey.. Speaking of this.. why dont we use the diffusal with an airstone but not the sponge? how do you think? :D
Ok, I made mine tonight, I did not like the unsightly plastic bottle in the tank so I used Fluval Bio-Foam cut a hole in it then I inserted the end of the hose that has a bubble stone on it in to the foam. I then put the foam in to a alagator sskull decoration so it is out of sight. The decoration is under the filter flow, so I hope it assists in stiring up the co2 bubbles.I will report on it later.
do you put that mixture in each of the 500ml bottles, or do you split that mixture in half for each 500ml bottle?
