    Hi,

    Does anyone know that the number below the dry chemical means? Eg. KNO3 I bought from Aquarium Fertilizer read 13.5-0-46.2, KH2PO4 0-51-34 and K2SO4 0-0-50. Thanks.

    It is percentage of N-P-K.
    The 13.5 is from only N, not NO3, BTW.

    KH2PO4 should be 0-52-34, probably a typo.

    More info can be found here (in "Macronutrient fertilizers" section).

    Thank you nipat and I've edited the KH2PO4 that read 0-51-34 so, it means 0% (N), 51%(P) and 34%(K) in KH2PO4 powder? Thanks for the great link too.
