    Hi,

    So I recently set up a planted aquarium, I added plants, rocks and driftwood.

    My question is, how long will tannins last (as I really like them, they make my tank look natural). I did a water change today and the tannins in the water have gone, will they come back?

    Also are they harmful to fish ?

    And finally I am getting a piece of opuwa wood and was wondering if that would release tannins?

    Thanks,
    Ethan

    Hi Ethan,

    Tannins are always in driftwood, and they are bene-"fishal" to the inhabitants.
    They'll come back after water changes. You're just taking them away by reducing the water.

    I'd assume opuwa wood will leak them into the water too.

    How long the tannins last depends on the size and type of wood

    Depends on the wood and depends on the fish. I am sure Mollys and other livebearers wont appreciate the lower pH while tetras and corydoras would. If you want to keep that natural look once the wood runs out of tannins then just add leaf litter.

    Ok, by leaf litter do you mean this stuff?

    Ok,
    Glad they'll come back, there not big pieces (that's why I was worried)

    Thanks,
    Ethan

    Ok,

    The pieces are pretty small but this opawu wood is medium sized.
