    Im growing Anubias in a hydroponic type set up, floating trays so roots are in water but leaves are emerged, humidity kept up by lids, daily misting with a hand sprayer etc. Plants are growing fine I'm just wondering if there is any advantage to CO2 injection to water when plants have access to atmospheric CO2 ?

    Reason Im asking is I Have had to reduce EI dosing ( with 100% weekly water changes as no fish to worry about). because with a full EI regime I get brown necrotic patches on the Anubias leaves which then rot away to nothing. I'm wondering if that's because CO2 is limited and ferts cant be utilised ?

    Not the best image of it but you can see brown patches on leaves in this pic...

    When I lower the dosing the brown patches go away and growth seems good...

    That's fungus, rot, etc, not ferts.

    Remove the lids, you need to have the plants dry out more.

    Mist daily etc, wet roots/ etc, but the leaves need to be drier.

    Note, not once did Anton ever see Anubias growing submersed in decades of West African fish collecting, not once.
    They were close to streams, but never in them.

    I'd grow them in soil/sand etc, tupper ware type trays, leave them open to the air.

    Thanks for that Tom, yes I have had much more success growing them emerged. Is there any benefit to injecting CO2 into the water when plants have access to atmospheric CO2 ?

    No, and it's more hassle/cost more etc. No commercial grower does this.
