  1. We are after as many aquarium plant images that we can get, doing so will assist us in completing the aquarium plant database.

    This is a good interesting paper. There's a lot mor evariation in natural systems, but this is pretty well suited for aquarium adaptation.

    The sediment really plays a large role as does the light/dark periods.

    Also, they cite Sand Jensen's 1985 paper, also a very good read for those interested in Gases like O2 and CO2 at the leaf surfaces vs the overlaying water.
    As you can see from that paper(Sand Jensen et al, 1985), there are huge differences.

    I wish they had measured the epiphyton and the plant uptake ratio of the NH4 and NO3 in this paper.

    Hi Tom,

    thanks for the interesting link. This study focused mainly on the nitrification and the denitrification, however, nitrogen uptakes by the submersed macrophytes, although only a small fraction, were not elucidated. Any comments on this issue?

    Regards,
    Erich

    Well, this alone was a lot of work, looking at the % of bacteria, then add macrophytes and you can subtract the % from bacteria, however, macrophytes often enhance the bacterial cycling rates via O2 additions and leakage of nutrients/glucose etc.

    So adding macrophtyes enhances things for both groups.
    Fungi as well.


    Regards,
    Tom Barr
