    Effectiveness of rain bar to distribute CO2?

    I've been using a rainbar to mist CO2 to the plants. It is now half the length of the tank, and I'm thinking of extending this to fit the whole length of the tank's back wall.

    I noticed that currently, most of the bubbles come out at the end, and hardly anything at the front (closer to the inline CO2 diffusor). I'm thinking, if I extend the rainbar, will it be an exercise in futility?

    Your thoughts and experiences sought. Thanks.

    Hmmm, I think you'll need a high pressure to push the co2 out and away from the rainbar. Why not attached the co2 tube to a powerhead?


    If you've learnt, teach, if you have, give.

    It is an inline unit so it needs to flow out through the water return.

    Plumb an external reactor then.
