    Rotalabutterfly.com has lots of info to get you pointed in the right direction.

    Also try https://www.advancedplantedtank.com/fertilisers-how-to.html

    There is a lot of variables to fertilizing a tank. Read as much as you can on every aspect of fertilizers, co2 ,lights, plants, soils, filtration/circulation, and lots and lots on algae.

    It's very rewarding having a planted tank, it's even more rewarding to learn and understand what your tank is telling you. You got this.

    250ml bottle for micro
    CSM+B 2g / each 2ml dose = .13ppm Fe

    250ml bottle for macro
    KNO3 6g / each 4ml dose = 7.35ppm NO3
    KH2PO4 1g / each 4ml dose = 1.39ppm PO4
    K2SO4 2g / each 4ml dose = 1.79ppm K
    MgSO4 3g / each 4ml dose = .59ppm Mg
    CaSO4 5g / each 4ml dose = 2.32ppm Ca

    Add CaSO4 last in macro bottle after everything else dissolves.
    Shake this 250ml container before drawing a 4ml dose since most of the CaSO4 will be in suspension in the solution.
    It will dissolve once in the tank.

    Please check these on an online calculator I ran the numbers rather quick.

    You have also not described a target for KH and GH levels in your tank.
    I'd recommend a KH of @ least 1dKH

    KH of 1 would be fine.
    GH of 4 or 5 would also work.


    The Ca & Mg in the macro mix could get you by maybe.
    That is why I included them.

    Worst case you could use baking soda to get a KH of 1
    240mg to 8 liters to get a 1dKH
    Could maybe add every third water change.

    8 liter tank correct???

    Sounds reasonable.

    If you do add Ca & Mg to macro mix it will add a bit more GH.
    Or omit the Ca & Mg from macro mix.
