Flourite....what is in it?

  1. tommy jr. Member Member

    I have looked around and find mixed opinions on flourite. Everyone agrees it is good but there is debate over if there are lots of nutrients actually in flourite or if it is just better at holding nutrients because it is cly based.

    The flourite site says it never needs replacing so to me that would suggest that it will hold / accumulat nutriens because if it actually contained nutrients to start with they would continually leach / dissolve out wouldn't they?

    SO WHAT MAKES FOURITE SO GOOD?

    Hi Tommy,

    All substrates will accumulate organics over time, as anaerobic bacteria will eventually grow in the substrate.

    Seachem Flourite: http://www.seachem.com/Products/product_pages/Flourite.html
    Here's the chart that shows what's in Flourite: http://www.seachem.com/support/GravelMineralComposition.pdf

    Eventually (despite what Seachem say) I believe all substrates will lose their mineral content as it is absorbed into the water column, and you will benefit from supplementing with Root Tab fertilisers.

    I have Flourite (black) in my tank, and love it.
