    Does anybody have any experience with pruning driftwood (Manzania) that is waterlogged and is in an established tank? Were there any problems with extra tannins leaching out, bacteria, etc.?

    After no responses I went ahead and pruned 2 finger sized limbs to no ill effect. After a few other issues settle down and the tank is stabilized again I will try some thumb sized limbs.

    I know you have come to your own conclusions, but I don't think tannins would really affect anything, they do sell it as an addition to tank water (black water powder), but anything leaching out would be negligible.Would many anaerobic bacteria be living in the wood? Can't say for sure, but in gardening when you bury wood under your seed beds (hugelculture) the wood needs nitrogen to decompose faster, so I don't think the waterlogged wood would support a huge culture of bad bacteria.


    I did did do a tank before without soaking the new wood and the worst that happened was a weird whitish bacteria grew on some parts of the wood, but it went away on its own accord after a bit.

    Thanks Kyalgae, when I first put the manzania in my tank I got the same white slime that eventually turned black and fell off. I did get some slime on the cuts but my oto cats have been working on it. I've just recently done more pruning and no issue with tannins. I had soaked the wood and changed the water repeatedly before putting it in the tank.

    Thread is slightly old, but I will share my experience. I have a dedicated gardena lopper that I use only for aquarium wood stuff.

    Classic Pruning Lopper 480B


    Maximum cutting diameter: 30 mm
    Length: 48 cm
    Cutting type: Bypass
    Upper blade: Non-stick coated, Precision-ground

    This works very well for previously cured wood, I do not do the trimming under the water, but rather at water change or rescape, I did not notice any extra tannins. No issues on dry wood either but do consider the diameter of what you are trying to cut.
