    Recharging purigen question

    What form of carbon do water plants use?

    Does anyone know for sure what form of carbon do water plants use? Some sources say that water plants are able to use aqueous form of CO2, but what exactly does this mean? Other sources say that water plants use carbon in the form of H2CO3. Thanks in advance for your answers!
