    Hi,
    This is my first planted tank and I am trying to figure out how much and of what to fertilize with.

    //////////////////////////////////////////////////////////////////////

    Tank size: 30 gallons.
    Lighting: Coralife 150 Watt 10,000k Metal Halide
    Lighting Duration: 12 hours at 5wpg
    Substrate: 3 Bags of Flourite
    Heavily planted with: Bacopa coroliniana / Hygrophila difformis
    Co2: Automated injection 30ppm
    Co2 Duration: 12 lighted ours
    Filtration: Fluval 304
    Temp: 76-78F
    Fish: 4 Dwarf Puffers
    Water change: Weekly

    //////////////////////////////////////////////////////////////////////

    My tap-water readings:
    TDS: not avail
    pH: 7.4
    NO3: 2.5ppm
    NO2: 3.5ppm
    PO4: with phosphates test kit? 0ppm
    GH: 143.2ppm
    KH: 107.4ppm
    Ca: not avail
    Mg: not avail
    CO2: not avail

    //////////////////////////////////////////////////////////////////////

    City tap-water readings:
    TDS: 376
    pH: 7.05
    NO3: 0.7ppm
    PO4: Total Phosphorous? 5ppm
    GH: 116ppm
    KH: as CaCO3? 78ppm
    Ca: 23ppm
    Mg: 14ppm
    CO2: Total Organic Carbon? 2.26ppm

    /////////////////////////////////////////////////////////////////////

    Aquarium water readings:
    TDS: not avail
    pH: 6.7
    NO3: 5ppm
    NO2: 0ppm
    PO4: with phosphates test kit? 0ppm
    GH: 165ppm
    KH: 71.6ppm
    Ca: not avail
    Mg: not avail
    CO2: 25ppm

    /////////////////////////////////////////////////////////////////////

    From Tom's report:

    A Typical Tank
    A typical routine for a high light tank with low fish load:
    Volume 80 liters (20 gal high standard tank)
    5.5 watts/ gal. - two 55watt 5000K/8800K lamps
    CO2-25-30ppm (I turn my CO2 off at night)
    Canister filter
    Fluorite (any porous iron rich material will do) about 7-10cm depth

    A Typical Dosing Routine
    1/4 teaspoon of KNO3 3-4x a week (every other day)
    1/16th-1/32nd teaspoon of KH2PO4 3-4x a week (every other day)
    Traces added on off days as the macro nutrients, so 3x a week, 5mls each time.
    SeaChem Equilibrium 1/8 teaspoon after water change.

    ////////////////////////////////////////////////////////////////////////////////////

    From this I gather that I need to adjust the Typical Dosing Routine to:

    1/4+1/8 teaspoon of KNO3 3-4x a week (every other day)
    1/16th to 1/32nd +1/16th teaspoon of KH2PO4 3-4x a week (every other day)
    Traces added on off days as the macro nutrients, so 3x a week, 5mls+2.5mls each time.
    SeaChem Equilibrium 1/8+1/16 teaspoon after water change.


    Am I missing anything here and are these the proper measurements to start my new tank to prevent algae growth?

    You have a great deal of light, this is more like 8-10w/gal since the HQI is very intense and efficient.

    Dosing every other day is needed.

    I'd add a touch more than the 20 gal example, I'd also suggest no more than 10 hours light time and crank the CO2.

    CO2 will be the biggest issue, see my post regarding that in the other sections.

    Regards,
    Tom Barr
