External Inline CO2 Diffuser Atomizer Aluminum Alloy for Planted Aquarium 12 mm

I love this diffuser. It takes less than five minutes to install, it’s pretty cheap and you get a good even spread of co2. No annoying diffuser or bubble trail in the tank. Just a good co2 addition with nothing in the tank to take away from your aquascape. I also love that you can buy a replacement diffuser disk. They provide you with a method for cleaning and restoring the pad with bleach. If you’re going to use bleach to restore the diffuser disk soak it in a cup of water with two caps of dechlorinating solution for several hours after bleaching it. It will prevent you from killing your cycle. This diffuser produces really small micro bubbles which is exactly what you want. You’ll have to use less co2 also as it’s inline and most of it is dissolving into the water on the way to the tank. It’s worked perfectly for me and I love the viewing window so I can check the disk and know when it needs to be cleaned. It’s not bulky and it’s made of high quality materials. You cannot go wrong with this diffuser. If you’re filtering your tank well, you will rarely have to clean the disk. If you add Purigen to your canister filter as the last media before the water exits, it will remove most of the micro particles which would build up on the diffuser disk and you can reduce cleaning the disk to a couple of times per year. Purigen only costs about $13 and will save you a lot of hassle. Great diffuser, fair price, easy to set up, built in check valve. Go for it. I highly recommend this product.

I recently decided to elevate my freshwater aquarium game by incorporating the Clscea External Inline CO2 Diffuser Atomizer into my setup, and the results have been nothing short of astonishing. The difference it has made in the health and vibrancy of my aquatic ecosystem is remarkable. The inline CO2 diffuser I chose boasts an elegant and discreet design, blending seamlessly into my tank without being an eyesore. Its build quality is robust and durable, assuring me that it will stand the test of time. The unit is easy to install and includes everything you need to get started, making it a hassle-free addition to any aquarium with an external canister setup. One of the standout features of this inline CO2 diffuser is its user-friendly installation process. Clear instructions and all necessary components were included, allowing me to set it up within minutes. It attaches securely to the outlet side of the canister filter. The primary purpose of a CO2 diffuser is to enhance the carbon dioxide levels in your aquarium, promoting healthy plant growth. This diffuser delivers on its promise, producing a fine mist of CO2 bubbles that get absorbed quickly by my aquatic plants. My plants have responded by growing faster, showing more vibrant colors, and producing more oxygen, creating a healthier environment for my fish. The CO2 diffuser creates consistently small and fine bubbles, which is crucial for effective carbon dioxide dissolution. It evenly distributes these bubbles throughout the tank, reaching all corners and depths without creating turbulence or disrupting the fish. This feature ensures that every plant receives the essential CO2 it needs for optimal growth. I have purchased internal Clscea CO2 diffusers for my existing high-tech tanks because they produce microbubbles. This inline CO2 Diffuser is much better in my opinion. I cannot recommend this CO2 diffuser enough for freshwater aquarium enthusiasts. Its exceptional design, ease of installation, and, most importantly, its ability to promote plant health and vitality, have turned my aquarium into a lush underwater paradise.

I use this with the fzone diy 5L tank, the fzone in-line diffuser would not work with this tank, not sure if I received a bad one or not, I did return that one. This one works excellent, I have it hooked up on a fluval 407. It’s installed at a slight angle, but works great, nice to eliminate the diffuser in the tank.

Works good. Only issue is the front view window traps air bubbles.

This thing was great to start... less impressed over time. It started to build up algea and debris on the diffuser disc just like the ones in the tank. I thought this one wouldn't since it was in the filter line; I also kept it covered from light but it still got build up. It took longer but alas, still did. Changing the disc requires you to open the line which means a watery mess. I ended up switching to a different system.

If you are looking for an inline CO2 diffuser, stop because you found it. It works very well and it is made very well, from what looks like pretty good quality machined aluminum. It's a very minimal and elegant design, and takes up virtually no space. I initially tried a different inline diffuser which was about six times the size for literally no reason. This one also has better connectors, standard, male double-barb hose connection. The other one used a single Barb with a threaded nut that is supposed to back out over the hose to secure it, but which only seemed to work to push the hose off the barb. Depending on the quality of your hose, you could probably get away without using hose clamps, but just use hose clamps. Search for "t-bolt" hose clamps if you want clamps that are a little more aesthetically pleasing than the regular worm-gear hose clamps. This goes in line, the last item in the return. You can see the tiny CO2 bubbles coming out of the return lily pipe and distributing fully in the water. I have two CO2 check gauges, one is the teardrop style that is about two inches above the bottom, and the other is a hang-on-board style tube. With a regular in-tank CO2 diffuser, the two check valves often do not match and they change as drastically different speeds. Since switching to an inline diffuser, they both always have the same reading and they change at the same time.

I been using co2 inline for a while now, the ceramic cylinder type one, i was a starting to loosing performance, I was due for maintenance.. So. While one is in service, I would have one in bleach solution for cleaning, so I tough why not purchase another one.. Based on Amazon recommandation and many positive review i had really high hope and excited to try this one.. Delivery came, started reading instructions, inspecting the diffuseur, I tried screwing co2 line into it for test fitting, screw it firmly and the tip broke.. Didn't even have the chance to try it out.. So just for that I would be giving it a 1 start rating for fast delivery... And minus 4 star for quality of product. Let's hope it's only a assembly or quality control problem and I was just badlucky, other user won't have water leak down the road 😉
