Love your work man. Thanks for all the info and experience.

I’ve always wondered about these. Thanks for the video!

Congratulations on 100k . Tbh I'm not sure when you hit it. But I'm pumped for you

I've used that particular reactor for over a year, it works great and very quiet. Plus like you mentioned, no bubbles in the tank.

This is exactly what I’ve been looking for thank you for this great vid

100.000 suscriptores, felicidades crack!!

Congratulations for 100k! 🥳 Also thank you for mentioning and your great Feedback!

Great video, MJ. I've been contemplating a reactor for a couple of my tanks as I too do not like the fine bubbles. It definitely makes my scapes a bit "hazy" during the midday peak hours.

I've always used these Sera reactors and the first thing I do is flip the top impeller so the forked section is at the top. It helps stir in the CO2 completely.

The reactor is pretty kool. I'll try it in my set up as well.. thanks for the video

you can help quiet the diffuser by making sure it's straight up and down, and you can remove the air from the chamber by removing the CO2 line but be ready to quickly replace the CO2 line or water will shoot out. I really like this channel and the host. thanks MJ

Always love the content you post, you have beautiful scapes! I’ve never had a Co2 setup, I just purchased a Fluval flex 9 and thought about running a small Co2 on it. Have you ever done a aquascape on a Fluval flex? I’d love to see you do a complete setup on one!

Thanks for sharing. Always wondered why ppl tend to put CO2 into the aquarium and not like you do into the filter exit side.

I use to have a sera Co2 reactor. My only cons with them is: -leakage around the joints -reduced flow/circulation They are a pretty good but I remember being frustrated with the leakage issue

I use this reactor too, just the bigger one. It's a great way to dose CO2. I had it hooked up to an Oase Biomaster 850 and it was too noisy, so I hooked it up to a separate Tetra EX800plus filter, and yes I have two filters in my 288l tank, the water is wonderfully clear :)

Been using these for years. Good product.

I totally agree that this is the best way to diffuse CO2. I've had regular diffuser, inline one, and now I use DIY reactor without moving parts and only sponge and ceramic to help the gas dissolve and it works excellent. No bubbles inside the tank and my 1,5kg bottle works since September on my 200L tank whereas it lasted for about 1month previously. I'd say if you have space in your cabinet you should totally give it a try.

Thank you for this vid. I too have an inline diffuser and was considering a reactor. I think you have made up my mind for me to switch over to the reactor. I appreciate you and your knowledge that you share with all of us.

Hey MJ i wish i would have seen this video a week ago i have a order coming from co2 art tommarrow with the pe regulator kit and inline defuser Being new to co2 disbursement in aquariums i have no experience using one. One thing i didn't want was a lot of extra equipment inside my tank, so i purchased the inline defuser. Now you tell me there are all kinds of micro bubbles in the tank that affect the look inside the tank, which i guarantee i wouldn't want that. So, change of plans. I'm going to get this same unit from Sera and go that route. As always, thank you so much for the great information. Also, congrats on the 100,000 subs. You deserve every bit of your success. P.S. i bought a shirt with the pyramid on it and had to have it. Take care, MJ, and go bless you. Peace brother.

Installed an Aquacare CO2 reactor a month ago to replace inline diffusion. The tank looks so much better without that constant mist of tiny bubbles. It's a huge improvement. Just in time to see my first tank really take off too! Back in November I had one horrible staghorn algae experience - it was on everything. So discouraging as a newcomer to the hobby, but you have to learn from your mistakes. Switching fertlizers, and increasing CO2 appears to have finally defeated it. Another small benefit of clear water is spotting the occasional tiny newborn cherry shrimp in the water column.

MJ great idea.....I just tried the same reactor and found by putting a piece of foam around the reactor it will take away 95% of the noise. Something similar to what you might use on a shrimp wall....3/4 inch thick...it totally worked...Just cut a straight line with a pair of scissors and place it around the mounting plate. I agree also it has to be level or it will make more noise...

I think I’ll start looking into a reactor as well. For years I’ve just put the diffuser directly below the intake to my FX5, using the canister as a makeshift reactor . Works decent, but it ejects a mass of CO2 bubbles a couple times a day. Nice work on the Channel.

I wanted to use co2 in my 125 gal tank, but the fluval diffusers didn’t put out enough gas I felt so I went with co2 reactor as well. I got a small sump that just pumps water already flowing through the sump to power the reactor. It’s gotten clogged a few times from snails, but after putting filter padding around the intake it’s been totally fine. Zero bubbles and looks great

Very nice. If I can give a tip. Get a really good high psi capable check valve. I use the co2 art one... i've had the cheap ones break on me numerous times or they just lock in one position over time.

Hey ! Hope you are doing well 😌 In my DIY Co2 reactor I tried also with bio media but performance is like 10% better but reduce the flow of that canister .. So in my opinion it is better how it comes.

Beautiful tank

I'm using reactor too, and put bioring inside reactor chamber to hold co2 a bit longer and giving more space for bacteria to grow

I got rid of mine due to the noise but the old version had only one impeller. Back to an inline diffuser which also makes the flow better than with the reactor. Another drawback of the sera reactor was the attachment that broke due to my clumsiness. It's a hard plastic and it breaks easily, the reactor itself is tough though.

Tip : just use the inline injector you have but on the inlet tube, not the outlet tube and tada, free CO2 reactor, the filter is going to do all the work. That is what i'm doing for over 2 years now, and you can reduce the CO2 injection by a lot because all of it is going to be disolved, no bubbles, space saving, CO2 saving and no money to spend if you already have a inline injector (and easier maintenance IMO)

Yeah 👍 had seen another video where an empty bottle is filled with co2 and kept inverted in the tank..Also I had connected co2 output to the internal water filter inlet get sucked in and the impeler disintegrates the co2 into fine bubbles.

I just installed a CO2 tsystem in my small 40L tank and noticed this as well. Great video as always. Tips for a video would be a horrible problem Im having right now and I cant be the only one. Hardscape that I glued together and thought was stuck, but started floating when I flooded the tank. So basically a video idea "How to solve floating hardscape after it is wet"

I had the Sera reactor and it's really good, but yeah I broke it! It was a bit noisy, mostly in the beginning but saved me some Co2. Maybe I should get it again 😁

Congratulations on 100k subscribers

I don't find the microbubbles to be that big of an issue. I also use In-line on my 70L scapers and I see very little bubbles actually. One thing to note when switching to a different CO2 diffusion is that you have to adapt your CO2 Output. Because In-line and Reactor offer a much more concentrated diffusion, you'll have to decrease your BPS, otherwise you run the risk of gassing your tank. I had that happen to me once, when I first switched to In-line diffusion, I didn't adapt the CO2 output from the classic In-tank diffusion method. In about a week, I noticed the fish started acting scared and had difficulties breathing. When I tested the O2 level in the tank, it was in the middle, so an orange-ish color, instead of the deep dark red it should normally be. The CO2 liquid was kinda old at that point so I didn't really trust the reading, but when I made a water change and saw it much more clearly, it was yellow. That resulted in a big PH decrease and the tank got partially decycled, which resulted in a considerable increase in Nitrites. Luckily, I lost no fish to that, as I acted very quickly by adding an airstone, did water changes and de-nitrified the tank with Seachem Prime (really useful product for situations like this, highly recommend it) which dropped my Nitrites back to 0 very fast + seeded the media with fresh bacteria by squeezing a sponge form an already running tank and adding Seachem Stability on top of that. Part of the issue was also because of the new external filter I used, which has a very finnicky glass inflow, that has very small holes, which very easily gets clogged up with debris and causes the Outflow to output a lot slower, thus decreasing surface agitation and flow. I say this a lot easier now, but it took me a really long time to figure out what was actually wrong with my filter. Countless sessions of troubleshooting, where I constantly cleaned the media, hoses of the filter, until I discovered that whenever I took the inflow out, it would naturally dislodge all the gunk, which would make the outflow work like new again, thus coming to the conclusion the Inflow was the issue. I still have the glass inflow now, but I clean it pretty refularly. I am thinking of switching back to the regular plastic Inflow that comes in the box.

Vaya, a mi me gusta ver las burbujas del co2 😂 cada uno es un mundo! Un saludo!

Can u do a an update of the big shallow tank? And i love ur videos u r my fav youtuber

Time to invest in one. I just hooked up a hose in my internal filter with a spray bar to diffuse the co2 XD

I was thinking about alternatives to diffusers myself, just because cleaning is a pain. Got to be an option for the next experiment. I saw some comments about plants preferring gas over dissolved CO2. I notice all the tanks in ADAs latest video have in tank diffusers, must be a reason they make that choice..

I’m glad you made a video on this as I am currently in search of a reactor. I have a 20G (75L) tank, and I bought the UNS Delta 60 filter because I thought that I would be using an inline diffuser at the time. I am now unsure which strength of filter to pair with the NilocG Cerges Reactor to not impact the flow rate. Any recommendations? Also, has anyone used both the NilocG Cerges reactor and the Sera for comparison? P.s. I reached out to both companies (UNS and NilocG and haven’t received much helpful information as they have never tested each other’s products together).

Beautiful tank. Is that narrow leaf java fern on either side of your tank?

Sounds interesting. Will watch later.

Congrats to 100.000 Follower

I ran this exact reactor for about 6 months. Pros: CO2 distribution throughout the tank was great, plants looked super healthy. CO2 test kit always showed positive results. Cons: Radically impaired flow rate of Oase Biomaster 850 by at least 70% despite having the biggest motor in the range. Had to add an another filter to add more circulation to aquarium. I guess you'll probably need a pump of more than 3000l/p/h to get a balance of flow rate and CO2 diffusion. Furthermore, the nipple for attaching the CO2 tubing is super delicate easy to break, keeping the reactor clean takes a lot of time. Conclusion: Gave up on the reactor. I run a cheap Chinese inline diffuser that gives similar results on a CO2 test, at a fraction of the cost and time spend maintaining a CO2 reactor.

Wow that seems really affordable. I think I'll try one

Great video as always, I did not catch it. Not drop checker? I would love to see a comparaison between this kind of reactor and a normal diffuser. Does de reactor gets the co2 level in the aquarium to the right amount faster? Just curious. 😊

I currently have a 5' - 120 gallon with a closed loop filtration. I use 2 Nu-clear canisters, one with polyfill mechanical filtration, and the other is lava stone biological filtration. I pump my co2 into my biological canister as a diffuser, so everything is inline and hidden. The co2 controller is on a timer and turns on 1 hour before the lights, and turns off one hour before the lights turn off. I highly recommend a controller to monitor the co2 levels and to maintain a consistent pH.

Wow.. never thought of doing something like this.. I feel that it has the potencial o mixing the CO2 in the water more effective.

I had one of these for a while, but there were two issues: 1. The nipple for the CO2 inlet is too fragile, it broke off after a couple months of usage. 2. After you clean this reactor a couple times, it will start leaking from the plastic cover. Otherwise, it works pretty well.

CONGRATS ON THE 100K SUBS!!!!

Use silicone lubricant on the prop shaft,will defo help with the noise

I really wish there were more nano-sized reactors. Two tips: 1) You can cut a donut out of sponge and fit it right below where the threads are on this model, and that does a great job of catching bubbles that might get past. Cut it so it's a little tight to the outside and a little loose on the center tube to make it easier to assemble. 2) if you splice a push-to-connect fitting (like the ones you see so often in RO/DI setups, it could be an elbow or a straight coupling, doesn't matter) between the check valve and the reactor, you can disconnect that fitting to purge air out of the reactor. You can also disconnect it when you're filling the bubble counter, and then you don't have to fight the twisting of the tubing when you're screwing the bubble counter on.

Thanks for the video. How do you connect the12 mm reactor to a filter equipped with 16-22 mm hose system?

I bought this reactor. The inlet hose broke. I was able to cobble it together until a better unit from NilocG. Even though this wasn’t a good value, I am completely sold on the idea of reactors.

i use that sera reactor as well way back ,surprised to see it still in production , there a weakness thou in the co2 inlet , break easily , what i do is to strengthen it

Bravo from Romania

Would be nice experiment, does reactor vs direct inline, inline via filter or in tank addition of CO2 make a difference? Nice vid again! Particular interested in inline via filter as the reactor by the way 😅

Yeah I used the same one and after testen almost all the other methods. The reactor is definitly the best! Mooi werk man! Door jouw filmpjes wil ik mn oude hobby weer oppakken haha

I have two 1000sera reactor on two biomaster 850 for my 750L , clearly the best way, i can’t have 25mg/L with in line diffuseur !

wow i’ve been thinking about getting a reactor for my 20G long…. i really dislike all the tiny micro bubbles as well. Most reactors need a really strong filter behind it so i never really got one. How has the Sera affected your flow rate? Did you notice a drop in flow? I’m using the biomaster 250 If you were to put biomedia inside the reactor- how much would you put? after watching this I’m thinking of making the upgrade!

I have a inline CO2 defuser, I can't get pearling to save my life, even saturated to the point it knocks my fish out. (yes i was quick enough to save them) I think it's because i have quite strong water flow. If i look under leaves i can see bubbles sitting there but only see bubbling float off fresh trimmed plants.

Nice video ❤️👍

I love your content so much! I will look into getting one of these! Quick question I have the Chihiros WRBG 2 as well. What percentage do you run yours on? I am always scared of running them too high because of algae but wonder if I am missing extra growth because of this.

Love your vids

i had this back then the rotating blades will stuck time to time, it leak easily so need to seal it with ptfe plumbing tape and the co2 nozzle breaks easily (fall, over tighten or out of the box), gotten frustrated with it after a few replacement and went with diffuser installed on the inlet of the canister filter.

amigo, que recomiendas? desde que momento se comienza a abonar un acuario plantado nuevo?

Nice new way

My shrimp did not like my the ph swing when CO2 would turn off over night. So I keep mine on. The regulator is attached to a ph monitor so the ph sits between 6.3-6.5 That reactor you have looks awesome. Love shiny things or things that spin.

I'm on team neo mixer at the moment, most of the benefits of an atomizer and way easier maintenance. I am not sure the neo mixer would handle tanks larger than 90p very well though, maybe even 90p is pushing it. Personally I can't see any CO2 bubbles looking at my tank straight on, for whatever reason I can only make them out looking closely from the side view so I am not bothered by them. All that being said I want to try a reactor eventually.

Nice video Mark! Definitely increases the knowledge a lot. Can you please tell if the filter flow was weakened?

I arrived at the same solution after using a ceramic diffusor. Couple things to mention: 1. The CO2Art diffuser is made of brass and coated with black varnish. Over time this varnish layer flakes off and the brass corrodes. DO NOT USE THIS DUFFUSER! It will release copper and zinc into your aquarium. 2. The Sera reactor has some design flaws: a) The tightening nuts for the hose attachments are too short/steep and the barbs have almost no lip , as the PVC hose relaxes, it will no longer hold it tight, leading to leaks and it can even just pop off. b) the reactor is made off acryllic (I think). Over time it gets brittle, and the co2 hose barb break off. c) The aquarium size that Sera gives for their two models (up to 500L and up to 1000L) is vastly overstated. If you aim at 35ppm CO2, they are good to 150L and 300L. Beyond that they start to „burp“

I had one of these, but it leaked like crazy one day.. so I switched to the art inline diffuser

Do a passive co2 video comparing active co2

What do you think about the green water labs - algae control? Is it worth it ?

Great video Mark I’ve been thinking about a reactor I have a black background so the bubbles really stand out! I enjoy the tank most the last hour before the lights shut off when the co2 turns off. Do you notice it affect the performance of the filter at all?

I was wondering if having a Co2 reactor helps better distribute the gas? I've noticed that with a regular diffuser maybe the micro bubbles don't reach certain parts of the tank as well as when it's going through the out flow?🤔 Does this make sense or is it just a silly thought? What do you think?

i prefer an inline diffuser any day over a co2 reactor

Ideaal om co2 op te lossen. Echter wees alert, deze Sera’s zijn erg fragiel daar waar de slangen op gaan.

What size filter is that? I always thought that the reactors needed a larger filter to be effective.

3:40 did anyone notice those absolute pythons!

Now that you had this for a while, did you notice the reactor slowing down the flow from the filter ?

What do you think about the fluval co2 kit?

Do you have a separate canister filter & CO2 cylinder for each of your aquariums? If not, what's the ratio? (What's the threshold?)

I switched to inline some months ago, jbl taifun. Im wondering, before I had the co2 come from the lowest place in the tank , but now from the outflow, which is near the top, like your lily pipe.The bubbels are smaller now but doesn't the co2 escape from the water quicker now? Your 'problem' seemed to be low in the tank so it looks it doesn't matter.

Hi MJ, you're using a reusable CO2 tank, where do you get it filled in Amstelveen area?

i used to have this it was perfect expect it lowered my water flow and the co2 intake part broke off.

Did you connect it to the inlet hose canister filter?

I've been using this reactor for years and it definitely is the best way to defuse Co2. Say goodbye to the Co2 micro bubbles.

Hey, MJ, here again. Question i have seen one of your subscribers suggest hooking up the inline defuser to the inlet side of your filter instead of the outlet side and using the external filter as your reactor. What are your thoughts on that. I've already ordered the reactor you have but came across this comment. i actually thought the same thing ok brother what's your opinion later, MJ

Hi. Have you noticed any change on saturation in all the hard to reach places of your tank?

I've had 2 of the sera co2 reactors but the co2 nossle break so easy it's annoying. I changed it to a dyi reactor much better

Did this reduce the flow?

You need to clean reactor every month. and change out flow like 30% less. I used couple months. I was not satisfied.

I've always heard that this reactor causes a significant slowdown in flow rate. What are your thoughts on that?

I have an oase filtosmart 100 and it is also making a little more noise than expected. Do you have any tips for silencing the filter, other than letting the bubbles out by tilting?

Fact is, all fish release C02 just as most animal life on earth does This occurs in their gills as it also does in our lungs So an aquarium functions just like in a pond etc in this respect. The plants and fish benefit each other, in an aquarium ....just as it does in the wild. if you have to add C02 the tank may not be balanced as in nature My tank is heavily planted and bit overstocked with fish. However, all fish are doing great as are the plants IMO it all comes down to weekly water changes to keep the nitrate level down.

Hast du den flüssigen Co2 plus von Tetra getestet?

What's the name of the green fine leaf plant?

Gotta love the autogenerated subtitles 😂 escape stink or scraper thing? Ahh scapers tank

I’ve wanted to try a reactor but I read that my filter is too weak for one. But maybe if I don’t fill the reactor with media it would be fine. I’m really happy with my in tank diffuser from Aquario and the neo mixer as well. I will never have an in-line diffuser again. A pain to maintenance and hard to tell when it needs cleaning which meant that I didn’t clean it often enough. Thanks for the video as always!
