    Hello eceryone..

    Looking for the ppl who can help me with some ideas regarding CO2 DIY reactor..

    If wolf (used to be his nick) is still around but with another nick plz let me know?

    I used to run the reactor from a filter inside the tank and worked very good. Now with the cannister im struggling to dissolve the CO2.. Put some small bio balls in to help but not there yet i tried to slow down the output of the filter and not dissolved yet?

    Any help will be appreciated to get a better dissolve rate!

    Ohw yes tried youtube and google but no help there..

    This is basicly the same as mine.. sorry not close to the tank now.. i used 500mm x 50mm white pvc. CO2 inlet at bottom. Connected to out flow side of filter.. threw in a couple of hands full bio balls that came with the tetra ex1200

    are your bubbles not to big with to start ? What about a diffuser / air stone in the tube - then loads of bubbles?

    Is the flow on the left being the highest point and the flow ot the tank the right being the lowest point that then loops back up into your return line?

    Could you maybe be a bit more spesific when you say it's on the output side of the filter. Do you mean that the filter is putting out water at the top of the reactor and then the bottom of the reactor leads to the tank?

    I think you might have a point there the CO2 goes straight into the line without being diffused.. The bubbles coming out of the spraybar is small but thats with half out flow..

    The flow on the right hand side where the spraybar is the highest flow because of the wavemaker. Weakest point at the right where in the inlet is.. "if im understanding the question";)

    okay here is a basic picture of how i set it up
    The red is the input to the filter. green output going through reactor back to tank. CO2 blue near the inlet of the rector
    orange is the bio balls :)

    Bingo!
    Try and get the water to force the bubbles down, you"ll get much better dissolving when you do that. Doesn't matter if you place the reactor on the input, or on the output (like I demonstrated in my sketch).

    I have mine on the input, it simply work better for me. Some people might be concerned about the CO2 having an impact on the bacteria in the filter, however, I have have never had an issue with it.

    Nevertheless, I will be changing my design so that it has an DIY inline heater as well, along with it's own dedicated pump to also add some flow to the aquarium.

    Keep us updated on how you will go about changing the connection to the canister and wether or not it helped.

    Another way would be to add it to the outflow. Look at the following sketch and tell me if your don't understand.
    [​IMG]

    To make it simple, you basically have to turn you reactor around, with the tubing as well.
    The water has to force the bubbles down as they try to reach it to the top of the reactor, and in the process of doing that, the CO2 is dissolved completely.

    Anything still unclear?

    Pretend you are the bubble ... and make sure that the path into your tank is the longest and hardest mountain peak you have ever had to free-climb.

Thnx a lot guys and girls.. Im just hearing a lot of water tumbling sounds inside the reactor wish i could see whats going on in there..

    Glad it's working good so far.
    The tumbling sounds are the bubbles dissolving, try and search some vids of clear CO2 reactors in action and you"ll see what I mean. Are the noises very loud? If so, what is your BPS set to?
