it would seem they actually dohave two pieces of driftwood, but they do not leak out tanins anymore
no. at some point in the life of driftwood, the tannins will leach out completely. however, if the water in a tank is tea colored as described above, chances are the wood is still leaching.unless your driftwood is fake, it leaks tannins in the water.
