    Hi AQ,

    My tank is 16'' x 10'' x 10 ''(40cm x 25cm x 25cm), co2 is nisso electronic 600, filtration is Atman 3336 (450L/hr).
    Plants comprises mainly of duckweeds, taiwan moss, microsorium sp.(a variety of ferns), nana petites and cryptocoryne sp.(a variety of cryptocoryne).

    Is it feasible to use a lighting of PL 24W(single tube) ? If not please recommend me a lighting.

    Thanks a million,
    zhan

    For those plants, you might want to go lower to a max of 14 watts. I'll prefer to put about 9-10 watts.

    Agreed, a clip-on light of 9 or 11w will be fine, looks good too!!!

    I see...my foreground plants includes dwarf hairgrass and C.parva, will 9-14 Watts be too weak for them to grow ?

    hi zhan,

    actually you can use 24watt pl tube, provided that your co2 is consistent and your fert regime is correct and consistent. Growth rate will be fast.

    Not forgetting the duckweeds' shade.

    The duckweeds does not cover the entire water surface yet and my fan tends to blow them aside, exposing direct light to the bottom.

    so what you have there is about 7g tank or 26 1/2L. 24w over 7g is by no meens high light, it is medium light and will require Co2 and ferts. I would put in some fast growers until the tank is balanced. Fast growers = algae battalion

    You call that weak.. lol.. wait till u see mine.. I run a standard 4 ft (4x1.5x1.5) and use only 80 watts of FL. and my foreground is growing app. It works well and gives me less headache than my 4x2x2.

    Hmm...I see. If I add more floating plants (duckweeds and salvina natans) and plant in japanese hairgrass(sort of fast grower?), will it settle the issue ?

    My fert regime:
    Aqumedi Floravit - 1.25ml every 3 days
    Seachem excel - 0.625ml every 3 days
    Seachem Potassium - 0.625ml every 3 days
    Seachem Iron - 0.625ml every 3 days

    I'll be planning to use Seachem nitrogen and Seachem phosphorus soon.

    regards,
    zhan

    I would like to dose excel everyday. Better if you can get seachem nitrogen and phosphorus. Or KNO3 and KH2PO4?
