    Hi all,

    We've got limited dry micronutrient options in Australia and the only one I can get access to is Rexolin BSP, which is similar to their APN but has more iron. Here are the figures:

    Typical BSP metal content (As water-soluble complex):
    - B: 0.4%
    - Cu: 0.3%
    - Fe: 7.5%
    - Mn: 3.7%
    - Mo: 0.2%
    - Zn: 0.6%

    Is it still suitable for my Aquarium using EI?

    What proportions should I add my 70ltre high tech high light tank compared to Rexolin APN, which is described on the EI calculator?

    Typical APN metal content ( As water-soluble complex ):
    - B: 0.85%
    - Cu: 0.25%
    - Fe: 6.0%
    - Mn: 2.4%
    - Mo: 0.25%
    - Zn: 1.3%

    Thanks for your help, as always :D

    I think the two big toxicities you want to watch out for are Cu and Zn. Any idea what it would work out to in ppm dosing EI?

    Seems fine compared to Rexolin.

    I'd use a tad more BSP.
    Maybe 10%-20% stronger solution.
