DIY Co2 for your Aquarium - How To

[@Lrhodes0809]

Please don’t stop making videos!!!! My husband is finally getting into the hobby, via plants. I have been keeping fish for years and now after watching your videos he is INTO aquariums! He is setting up his own tank, you have brought great info in a way people can relate to, please for love of all things good, don’t give up!!!! Wish I had found you earlier. Keep making videos and keep on!

[@TheWaterBox]

Haha that is VERY awesome to hear! :) Is he still going at it?

[@Lrhodes0809]

The Water Box yes, he is having algae issues, but he is trying to figure it out. ☺️

[@TheWaterBox]

@@Lrhodes0809 Algae is usually common on new set ups. He has to ride the wave and keep thing balanced out but people usually figure it out! :)

[@Lrhodes0809]

The Water Box yep, that’s what he he trying to do now. He is trying to figure out the imbalance, so he can fix the issue at the root.

I love your videos! Fast, informative, lots of extra info and extra gadgets with links you tell us about and the sarcastic jokes are my favorite!!! Thank you I always get so much more from your videos in less time then others that drag along & frustrate me showing obvious steps that could have been just said instead of demonstrated. I’ve already used two of your videos for a dirt tank and CO2 in just 24hours.

thanks for watching!

[@damicolicious]

This is the best and most thorough video for instructions on how to use this DIY setup. We use these in indoor growing to add Co2 to our grow tents.. very informative, thank you.

[@TheWaterBox]

Oh nice! You just release it into the air in the tent?

[@damicolicious]

@@TheWaterBox Yes Sir, my growspace is 4x3x6, so this keeps a steady and light flow of co2 in there and the plants love it. In fact I received the exact rig you use in this video in mail 2 days ago and I'll be setting it up today.

Thanks! i'm glad you enjoyed!

[@techpro8391]

The diy co2 system is $6 on Amazon right now (same as yours), Tailonz Pneumaitc selenoid is $11. I also recommend you to get a better needle valve (Rhinox copper needle valve is a good choice). You can also get citric acid online for $70 50 lb. I've had it for about a year, lasts on average 2 weeks 1.5 - 2 bps, 50 gallons. I have 20+ kinds of plants, including red ones. It works pretty good.

I can't seem to locate one, but do you have a video where you show exactly how to set up a basic co2 system?

[@RexClair]

I’m starting up a nano tank and I want a Monte Carlo carpet. I don’t have a lot of room where it’s going, but I would like to jumpstart this carpet. Would this system be good to run a couple of weeks to try and get the carpet started?

[@TheWaterBox]

It'll help for sure, especially in a small tank.

[@marykateolson8951]

Quick question. I set it up. There is pressure and a reaction, but my needle valve is not controlling flow! Do you think I might have a defective unit?

[@TheWaterBox]

That needle valve is very finicky and just have to be adjusted very slowly.

[@RaccoonCreekAquatics]

I have the pleasurized co2 system with paintball cylinder. To me, it's worth the price. Great video and information!!

[@TheWaterBox]

Yeh I love them pressurized set ups too! :) Makes life so much easier. But when I'm in a pinch and set up a new tank, this is a good quick go to way to get co2 into the tank.

[@billykettner3004]

Great video, thanks for posting! Any idea how long it takes to see results?

A week or two you should be seeing your plants to much better. When you give them Co2 they will grow more lush, more vibrant. Thanks for watching!

[@amanbakshi2265]

Hi, Any suggestions why citric acid bottle pressure is going up around 2 very quickly? Thanks

[@JJ-px5wy]

I love your videos, they have helped me a lot. I have a question I did the setup and everything is working fine but when I touch the bottles it looks like they have built so much pressure inside. So what are the probabilities that these bottles would explode, I’m scared since my aquarium is in my room.

[@ebe2278]

Your bottles should be fine, they are tested to around 150psi which is round about 10bar pressure. I would imagine the tubing would blow off first!

[@TheWaterBox]

You are fine. Those soda bottle are rating to handle way more pressure than what the DIY mix can produce. Your hoses will mostly likely pop or split before your bottle do. Just don't go dropping them.

[@76Stankfinger]

Great info. I’m gong to try this next.

[@TheWaterBox]

Awesome! Good luck!

[@maj84]

I have this same setup and it works great. My only issue is that when i refill the bottles, it takes hours for the pressure to build high enough to start diffusing into my aquarium. Even after ive squeezed as much acid into the baking soda mixture as i could. Is this normal?? There don’t seem to be any leaks

[@TheWaterBox]

It shouldn't take that long. Do you have a one way valve in the hose line? Maybe try changing that out.

[@GGRetroRally]

Hi there, Really helpful set of videos thank you. I purchased the diy co2 system off amazon. I also purchased the electronic solenoid so i can set up a timer with it. One issue i have is that the thumbscrew that comes with the DIY CO2 system is really hit and miss. I'll set it up for a number of bubbles in the bubble counter then ill check it an hour later the number of bubbles will be different. is it that the thumbscrew is broken or do i need some sort of pressure regulator? thanks in advance

[@TheWaterBox]

You have to keep fiddling with it. The problem is they aren't always built the same. But it's DIY, you can get away with a higher then normal 1BPS kind of flow. It's also the beast of the nature with dealing with DIY Co2. The pressure will lessen as the pressure is less i the bottles over time.

[@michaelfischer6984]

@@TheWaterBox Bubbles vary because the pressure cycles. 1 bubble per sec is the same amount of co2 for diy and pressurized systems (after the initial 2 liters of air are purged)

[@JYeungTV]

Just found your video and literally got into the DIY. testing out the 1 bubble/sec for now but I was wondering...does it really matter where the diffuser is placed in the tank?

[@TheWaterBox]

Yes. Put it in a place where there's flow or the co2 isn't moved around the tank. Co2 tends to concentrate at the top level of the water. You need to move it around the tank for maximum efficiency.

[@haydenm2397]

Beautiful video, thanks a lot 👍🏼

[@sniper25rider49]

Hi I have this DIY co2. I run it for 8 hrs. After using this Co2, I run my air pump in the next 3 hrs. And repeat the cycle in the morning. My question is, do I Have to open air pump after using co2 in w/c I see the fish gasping for an air. Or not to use the pump for the Co2 I inject will lose. Pls help if I’m doing it right.

[@TheWaterBox]

I'd use it while the co2 is going. The air pump doesn't "inject" o2 into the tank. It helps create surface agitation in the tank to promote oxygen exchange and you want that so you don't gas your fish.

[@Validatority]

Hi, i am hoping to try a acid based diy co2 set up. A question about the types of PET bottles. I have access to two types of PET bottles where I live. One is stiffer kind of plastic and the other is softer. Considering that I would be using a solenoid and shutting flow of co2 off at times, which kind of PET bottles should I use?

[@TheWaterBox]

I would not know as I'm not too sure why kinda of bottles you're talking about. We here in the US use the 2-litter one for soda.

[@Validatority]

Thanks for your reply. Understand that it can be hard to visualize. Perhaps this is an experiment for myself to try

[@legainnamchyo4836]

Hey! Do I have to shake the bottle again when I have to use it the next day as my baking soda has been settled down as a sedimentation over night.

[@TheWaterBox]

You shouldn't have to. You don't want to. The reaction is paused when you close the needle valve. When you open the valve back up, it'll start the reaction where it left off. The only time you want to shake the bottle is when you are mixing a new batch.

[@BigDavos]

Thanks! Glad to hear that!

[@soggyfries4347]

@@TheWaterBox The needle valve crapped out on me leaving me the inability to to adjust the flow rate. So when I reach 1 on the valve its just flowing full speed. I know its a diy setup but dont wanna risk giving the residents their last "nighty night."

[@angelahernandez5506]

Can you use one of these C02 systems for multiple tanks?

[@TheWaterBox]

I wouldn't. The pressure created by this process is not consistent. Pushing it out to multiple lines probably won't yield any good results.

[@relicpassion]

Once you turn off the valve at night, is it necessary to lift the needle valve, from citric acid mixture.Some say taking out the needle valve stops the reaction and you have to prime the mixture the next day.Please explain.

[@TheWaterBox]

Well, if you HOSE (I'm assuming that's what you meant) from the citris acid bottle, then yeh, it stops the reaction since the acid can't get into the other bottle to react. And if you do that, yes, you'll have to repime it the next day because the pressure stopped pulling the acid into the other bottle.

[@karolinazmoka5646]

Is any different way for switch off at night ?

Hi..i would like to ask if this diy co2 shall release another chemical / somehow affect the TDS reading?.. Fyi, i am now using this diy co2 for a week..cut story short, while at night, co2 is off, tds increase about 3-5ppm..(i compared the reading yesterday evening against this morning) But during daytime while co2 is on, tds reading increase 9ppm in 3 hours.. is this normal?.. Thank you

[@TheWaterBox]

Tour TDS is increasing because your carbons are increasing when you inject co2. It's normal.

Okay, you convinced me, I'll just get the setup and a five-pound tank. It is almost as cheap.

LOL. In the long run, it really is.

Hi great vid Question can i use 2 defuser in one setup? Thank you

You can if you want. Is it needed? If your tank is small than 40g, then most likely no.

@@TheWaterBox hi thanks for replying i am thinking to use one solution to two 5 gallons tank, is it ok?

[@TheWaterBox]

@@LearningIsTheBest You mean splitting the setup into two tanks? That might not work too well. The pressure coming out of the bottles is inconsistent as it. Splitting the line will cause more inconsistency. You can try it but I'm not sure how well it will work.

@@TheWaterBox ooh ok, i guess i will try, as soon as i can set up the co2... thanks thanks

Hello, I have set up a dirted tank with organic seed starting soil capped with 2 inches of sand with a filter and heater. I don’t have any plants or fish in it yet and I can’t seem to get it to clear up from it’s apple cider looking water. It has gotten better with water changes but it seems like a waste. Do you have any ideas for what i could do?

[@TheWaterBox]

It's tannin's from the soil. It happened. It goes away over time with water changes but you can use Purigen in your filter and it should help clear it up pretty fast. Just take it out when you're done with it so it doesn't take out more stuff that the plants may need.

[@robbyjones9489]

Thanks, I’ll try that out!

[@TheWaterBox]

Good luck!

[@jimmyhyde117]

Thanks for the information. I've been running a similar setup for about two months and my solenoid has gotten clogged up with crystalised baking soda. Has anyone else had this issue? Any suggestions on how to prevent this problem?

[@UltimateKaploger]

Hello! Very helpful video, I just have one question: I'm doing some research online on having to use both co2 on my planted tanks WITH airpumps. I'm getting mixed info's and I was just wondering if this is something you'd recommend? Thank!!!

[@TheWaterBox]

You're fine if the air pump isn't drastic and causing massive surface tension. You want subtle surface movements even using Co2 to promote the gas exchange balance so a subtle air pump is fine.

[@UltimateKaploger]

@@TheWaterBox sweet! thanks!

[@JLCD905]

Does the needle point have to exactly be in the green zone to be considered primed? I've done it myself using the exact same measurements of Citric acid, baking soda, and water too. What happened on my end was that the needle spun just a little past the green zone but not very far off at all from the green zone (steady at the 2.20 mark)

[@TheWaterBox]

No, just get it up to the green is fine. It'll slowly build more pressure over time and most in the the green zone later. Just get it to at least the line is fine.

[@Damian-Mucha]

Hi, so if You shut off the needle valve during the night will the pressure in the bottle not build to dangerous level, I guess it is still safe pressure but can someone please confirm?

[@TheWaterBox]

If you shut off the needle valve, it's SUPPOSED to stop the reaction from happening before there's enough pressure to split a 2 litter bottle. I explain it in this video: kzbin.info/www/bejne/ZqPWmaiZhbdrnsk

[@cjjones2676]

Great Video, but will you recommend this DIY Co2 over Pressurized co2? tnx

[@alanjamessaldana5006]

Hi chung (hope i got that right). If i doubled the mix, say 400g to 1200ml citric acid and then 400g to 400ml baking soda, will it make the mixture longer before i prime one again. Its currently taking me just 7-10 days. Thanks mate!

[@TheWaterBox]

I dunno. I don't know if you'd want too unless you double the size of your bottle too. Don't quote me on this and I'm guessing but doubling up on the mix might double up on the pressure too. I dunno though. You'd have to research that or asking done else who's tried it or looked into it. I don't go the diy co2 route anymore. Its either passive like the Fluval 20g kit set up or pressurized or no co2 at all. Depends on set up of the tank.

[@alanjamessaldana5006]

The Water Box I think your right on doubling the bottle size. Problem with that is that i don't know if there's any 4L bottle, and if there is one, if it would fit the co2 bottle caps. Oh well guess ill stick to this setup until i get tired, or find a bottle! Cheers!

[@TheWaterBox]

Yeh, there are some limits until someone finds a better way.

[@TheWaterBox]

I never had a problem with the pressure inside the bottles. Neither does Pepsi or coca cola or other soda companies. I dunno what the max pressure on a sealed bottle is but on a diy system, it's not completely air tight.

[@IncurZeAwperator]

Generally soda bottles are pressurized around 50 psi and u can drop them and shit and they are fine so i assume u could push 60 and be fine

i always wanted to use diy co2 but will it change the ph? I got discus and rams in it.

[@TheWaterBox]

It will slightly (not as big of a swing as pressurized co2) but for discus and south american rams it's a good thing. How soft is your water now? How big of a tank?.

[@BuurmanHans]

im running this system for 5 days now, but the pressure is increasing to 2,2 kg/cm3. is this a problem or am i just fine. im a bit concerned since its out of the green range if you know what i mean.

[@TheWaterBox]

You should be fine. Soda bottles don't fail until over 7 kg/cm2. Your hoses split or pop first but typical vinyl hoses can at the minimum stand up to maybe 4 (depends on type and make). Most likely will pop out of it connection first if anything but you still go a ways to go. If you're still worried, just let a bunch of the co2 out in one go.

[@TheWaterBox]

I guess make sure you have the mix right. DIY Co2 rarely every kills kills fish. The concentrationg isn't pure enough, especially in larger tanks. In smaller tanks it can happen easier but again, rare. More important is not getting the mix into the tank itself. Again, rare. You have to do something really stupid like squeezing the bottle on purpose into the tank. MAYBE if the bottle tip over so there's that.

[@marlonallansupetran7120]

I was not able to buy the needed materials to build one before the apocalypse happened (COVID home quarantine). Are there home materials I can use to somehow supply my tank with CO2?

Air stone will help a little

[@busker_boy_c2845]

Also if u don't have much co2 reduce. Your lighting on your tank as less light less photosynthesis less photosynthesis less co2 used id drop it to 5 hours of light a day or less

[@TheWaterBox]

Materials as in making the contraption or the mix (Citric Acid and Baking Soda?)

[@marlonallansupetran7120]

Hello, I've read that this kind of system (citric acid + baking soda) tries to maintain an equilibrium. Reaction in bottle B adds pressure to both bottles and when there's enough pressure in bottle A, it send more citric acid to bottle B, and the cycle continuous. My question is, isn't the cycle just going to continue and the pressure will build up even when the line going to the the tank is shut off? I am currently doing the sugar-yeast method but it runs out far too quickly and and I could not shut it off, so I am thinking of switching to this mix. Thanks!

[@TheWaterBox]

You just answered you own question. When the Bottle A pressure gets higher than B then it send the acid over. But if you stop pressure from escaping from B, then it'll always be pressurized higher then in A. Besides, a bottle can handle 1200 psi of pressure. Your DIY contraption or tubes will pop before the bottle does. Might leave a wet mess though (more if you don't have a one way air vavle).

[@TheWaterBox]

To clarify, when shut off, the pressure will build to the point where both bottles will have equal pressure so nothing is moving into either bottle. That initial build up before it stops isn't enough pressure to go beyond 1200 pounds.

[@marlonallansupetran7120]

Thank you for responding! I get it now, the key word is equilibrium! When the solenoid shuts off, neither bottle will be able to send anything to the other, wether the gas from bottle B or citric acid from bottle A!

[@TheWaterBox]

@@marlonallansupetran7120 It will for a little bit when you shut it off but once it equalizes, then yeh, nothing moves. Everything is in balance. ;)

It'll rise over time, especially when you cut the connection to the bottles. You should be fine. Those 2 litter bottles are made to handle was more pressure that DIY c02 can produce. Assuming you're using the right amount of mix.

[@shadowkirugaming6738]

You can try. Probably cause noise form the gas you inject into the filter.

[@tthimsel]

I thought that we cannot use Solenoid Valve for DIY CO2 system as it would build up pressure in the plastic bottle and cause issues/ Is this actually safe? What is happenning to the pressure then?

[@TheWaterBox]

Once it's cut off, it should stop the pressure. As long as you have bottles that can handle the correct PSI, you should be good. More on this here: kzbin.info/www/bejne/ZqPWmaiZhbdrnsk

[@TheWaterBox]

NP. Just leave comments there if you have any other questions.

[@vanqz5692]

Wouldn't shutting it off at night cause too much pressure to build up in the bottle?

[@TheWaterBox]

I never had a problem. The bottle are meant to take on a lot more pressure and the co2 contraption on thses DIY sets will usually give before the bottles would.

[@gt.tutorials577]

Can I use co2 splitter on DIY co2 system?

[@TheWaterBox]

?You can, I just don't think it'll be too effective. The pressure coming from DIY co2 aren't all that reliable.

[@jordanyang3066]

Going to use this for an outdoor grow/breeding tank.

[@TheWaterBox]

Great! Good luck!

[@jordanyang3066]

The Water Box On second thought I'm just going to do a paintball tank and take a chance on Chinese regulator. I really want a uns mini but its sold out everywhere.

[@TheWaterBox]

You'll usually do fine with a chinese regulator. I have had great luck so far our of the 5 times I bought them.

Can you use co2 cartridge for guns in an aquarium? Thanks

[@TheWaterBox]

Sure? Depends on what you're going to do with it.

[@hannecesito3423]

@@TheWaterBox i had a co2 system from ista for my nano tank using 12g cartridges but they phased it out.... i was thinking if i could buy the ones used for pellet guns and use that? Im not sure if co2 for aquariums need to be food grade ones....

Hi i tried doing this but I can’t seem to control the air valve that much. Also the bubble counter seems to empty out and move the water that’s inside the bubble counter back to the tank and the bubble counter is empty with a little water left but no bubbles are forming

[@TheWaterBox]

Are you using a DIY kit?

[@__AT__0]

The Water Box yes it’s the same exact one that you are using in this video.

[@TheWaterBox]

Hmmm. I've not had too much trouble with the valve but it is a little stiff making it hard to dial in. I'm not too sure about the emptying of your bubble counter though. Maybe you're blasting the co2 it'll happen but you would know if you were blasting it or not.

[@__AT__0]

i'll find out more information about the bubble counter and i'll let you know!

[@TheWaterBox]

Cool!

[@4funrc11]

Hey, Great vid! Thx! I'm going to try the Anself DIY CO2 (D501) generator/system on a 20L. *Would you / Could you pls* do a review on the newer D601-S model? No more plastic drink bottles, self-contained stainless steel canister with (some) electronic solenoid ON/OFF regulator for around 89 to 99 bucks. TIA!

[@TheWaterBox]

If I ever get one, I would do a video on it but I mostly run on pressurize co2 now for all my tanks so I'll probably never need to get one.

[@HogwartsBasement]

If anyone cannot find citric acid powder use lemon juice with some water works just as well and gets the device up to 2 bar ish

[@TheWaterBox]

Thanks for the tip!

[@victorameduri3227]

[@joydas4442]

The main problem I am having with yeast sugar mix co2 is an effective way of diffusion. Glass diffuser won't work properly. If you can provide me an effective DIY co2 diffusion method that will be very helpful.

[@TheWaterBox]

Glass diffuser always worked for me but I'm using a Citric Acid and Baking Soda mix. It sounds like you're not getting enough pressure out of the reaction. Yeast+sugar I find to be a pain to do. How do you have it set up? One bottle or two bottle set up? How are you mixing your yeast/sugar with the water? You're using hot water so it properly dissolves the yeast/sugar?

[@joydas4442]

I am using warm water to mix 250 gm sugar and 2 small spoon of yeast in a 2 lit bottle. The reaction is fine because I am getting 2 bubbles per sec for first 5 days. After that it decreases.

[@Robert_K1]

I just set up a yeast/sugar mix the other day. One half liter bottle only. I have the same problem regarding the diffusion so I have the tube going into my internal filter. It's only a 10g tank but works great. I'm curious to see how long the mixture will last (1tsp yeast to 1tblsp sugar). I'm sure I'll upgrade to a baking powder/acid setup but I'm just "getting my hands wet".

[@Jude-to7lw]

Can you use a 1 L bottle?

[@TheWaterBox]

You have to find a different recipe for the mix for 1 litter bottles.

[@TheCountSummon]

Hi, I also purchased one of these DIY CO2 setups (still waiting on my diffuser and for my dry start to finish). Would it be possible to, instead of using a solenoid valve, add an air pump on a timer to make the CO2 diffuse faster overnight in order to guarantee the safety of any aquarium fish?

[@TheWaterBox]

The concept is sound but I can't say for sure as I've never tried it. I couldn't tell you if the air pump will diffuse the co2 away enough. Sorry 😒

[@TheCountSummon]

All right, thanks. :)

[@topbinsfootball2664]

I accidentally added 600ml to the baking soda mix as well as the citric acid mix, is this a massive issue?

[@TheWaterBox]

Yeh it's too much and you might not get the results you want.

[@shadowmancer2657]

Sir, I wanna ask, will the Vinegar be as effective as the citric acid as a substitute in creating Co2? Hope you'll notice my question.

[@TheWaterBox]

I've never used that combo before in this kind of set up so you'll have to google it and see if there's a recipe out there for it.

[@shadowmancer2657]

@@TheWaterBox thank you sir

[@Daymianpac]

Hi. I'm trying to set up a planted tank. and I am looking to buy pressurized co2 system.. although my budget is around 100. Most of the systems I see online are 200+ including all the equipments necessary.. would you be kind enough to send me link for co2 tank that cost only $71 in your video?

[@TheWaterBox]

The best you probably can do is around $120 for just the regulator and a tank. Just check on ebay or amazon

[@ungahaayah9565]

May i just mix the citric baking soda and add water and let the reaction happen to let co2 into the tank all in 1 bottle

[@sdmfbastard]

I think if it all mixed at once the pressure would explode the plastic

[@TheWaterBox]

It won't last long. And it'll just create so much pressure you'll just lose all of it in a hour.

[@zarehchahinian9721]

Just a question is 2L bottle a must, or I can do this setup with 1.5L bottles

[@TheWaterBox]

I think yo might have to adjust the mixture. You'll have to google it.

[@MP112791]

Can you split diy co2 between 2 tanks?

[@TheWaterBox]

You can, I'm not sure how well it'll work. Never tried it.

[@NikolaGrigorovNG]

Hey, do you still use the system? Is it working all right. I think it is cool but i am not sure how it will be in the long run.

[@TheWaterBox]

Yeh, it works. It's jsut a paint to keep mixing a batch every 2 weeks. If you don't mind doing that, then yeh, it will work great.

[@NikolaGrigorovNG]

Sure, but maybe that depends on the size of the aquarium. Mine is 3 gallon, shrimp tank and has 1 bubble every 4 seconds, so I expect it to be more durable. I read that the valve dies after a while, but it is not that bad. Very informative though. +1 subscriber :)

[@TheWaterBox]

Hmmm... the valve never died on me. If you use too much force on the valve (twisting hard) I can see it breaking. If you're running 1 bps then it will last longer for sure. What kinda of plants in the shrimp tank? And thanks for subbing! There's also another solution to co2 for a 3 gallon tank but might not work for that size for what I will be talking about. Watch for video in the morning. ;)

[@NikolaGrigorovNG]

Now i have java moss, anubias nana and planning to add some dwarf baby tears.

[@TheWaterBox]

The first two plants will do fine. Dwarf Baby Tears? Are you sure you wanna go that route? Or do you mean just normal baby tears?

[@flamingbridges1649]

I bought a co2 kit for my 30g which uses the usual sugar and yeast. I set it up correctly and I'm still not getting any bubbles coming through. it's been set up for 4 days now. and since I paid £40 for it, i really want it to work

Wrong type of yeast.

No. Won't give enough for something that big. It'd be a nightmare to maintain for something that big. Just go pressurize tank set up.

[@DreamCatcher-fz8wj]

Is it necessary to use 2 litre bottle? Can I use 750 ml bottle?

I'm not sure about that honestly. I think the measurements would have to change on the citrus acid and baking soda. That I'm not sure about.
