Thread: CO2 Diffuser

  1. Default CO2 Diffuser


    0 Not allowed!
    Hey guys,
    Quick update/question on my DIY CO2 setup. The recipe is great, the bottles are going well without any leaks. The diffuser, however, is a problem. I started out with just a cheap, small airstone, which released a lot of little bubbles into the tank. Then I tried a passive CO2 bell based on this, which worked well, except that I didn't have a good way to fasten it and it kept coming undone. So, I finally just bought a glass nano diffuser, this one. Now, in the picture, see those little bubbles coming out of that diffuser? I wasn't getting those. I knew my system didn't have any leaks or anything, and I didn't know what could be the problem. So, I drilled a small hole in the diffuser. Now, every once in awhile, when the pressure has built up, a large bubble or two will release from the diffuser. I know this is not ideal, and not what I had in mind. However, since there is now water in the actual diffuser (because I drilled the hole), is it acting like a passive diffuser like the one with the bell? Or is the only CO2 escaping and diffusing, the CO2 in the bubble released? Was I too impatient before I gave up on it in its original state (I waited 2 days)? Is it just cheap product, or Does it need DAYS worth of constant pressure to finally work? Or are the bubbles too small for me to see? Should I super glue the hole back up and try again with the diffuser, or start experimenting with other methods? I'm trying to avoid putting, for instance, a whole water bottle in the tank for diffusing purposes, but I'm getting to that point. My plants need it. Thanks, feel free to inquire about anything else.

    Those diffusers might need more pressure to work than you DIY CO2 bottles can produce

    If you have a canister filter, you could try a in-line diffuser like the below. It requires a lot less pressure to work. I have been using one for some time now and I really like it

    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    That's good to hear you say that. Also unfortunate. Too bad I have HOB's. :(

    You could try a venturi on the outlet of your pump. I use that and it works very well. I do have a powerful pump though. A small venturi might still do the trick

    The pump I have is rated at 900l/h.

    This is its diffusion capability uploadfromtaptalk1406380151593.jpg

    What is your HOB rated at?

    What about a simple reactor like the below? You would just have to add a small power/pump for it. It should help to almost create a suction into the camber allowing your CO2 to flow freely

    Did you make one yourself? I didn't even know what a venturi was, so I had to read a bit LOL. I don't actually have a pump right now, so that might be first on my agenda. My HOB's are an aquaclear 50 (200 gph) and an aqueon 30 (also 200 gph). I used to put the CO2 into the intake of the filter, but I heard that the bubbles were bad for the impeller. In your photo, where did you get that attachment that the airline is hooked to? Or is that the venturi you were talking about...
    Cliff, I took a look at that link and the attached diagram on the pdf. So, the water pump would take the place of the canister filter, and the whole diffusion would take place outside the tank, with the pump circulating the water back into the tank? Just making sure I'm understanding this correctly CO2 diagram diffuser.JPG

    I have only seen them used inside a tank with a Maxi-jet pump (a 1200 I believe). According to the manufacturer, you can use it externally, but I have never seen it used in that way so I can not offer any advice on that.

    I thought using it inside the tank (behind some plants to hide it) as you don't have a canister filter

    My pump actually came with a venturi. Yes it is that clear thing in the photo that is attached to the airline. The 45angle was something i put on in order to direct the flow a bit better.

    Not sure where you could look for one. With that pump rating I would be extremely surprised if it didn't work.

    Update! I haven't abandoned this thread. So after looking at pumps and looking around the internet a little more, I came across this . I tried it out today since I have an aquaclear, and it's working so far. We'll see if there's any change in the plants. I didn't have to buy a pump for this one and I didn't have to mess with my stupid ceramic diffuser that I bought LOL
