curiosity on the 'shelf-life' of driftwood in a tank
i could guess there isn't enough tannis to last the life of the tank
i could guess what tannis is in the driftwood will leach out into the water and not be replaced in the wood when it's gone.
i know certain pleco's have a diet that requires wood (not all but some)
and there's pH things and the rest of it going on with driftwood/tannis/tannic acid ...
aside from people being unsettled by the tea color this can turn the water.
i have heard mention of tannic acid being beneficial to tanks (including from somewhere dianna walstad) - if unsure and you know a little, go with the biggest name in the hobby you know of that has mentioned it :)
am i worrying too much about having tannic acid ?
is this something i could consider replacing driftwood on a regular basis if there is a bonus ?
is this something i should stop worrying about ?
if replacing it for any benefits it may have, ... how often ?
1 year ?, 6mo ? 2 years ?
i dono, just fishing for answers to a sudden curiosity
