| There are three types of wood you might find as driftwood. The first is what you want, real driftwood. I've also seen grape vines sold as driftwood; you don't want those. The worst was one I ordered on-line. It turned out to be hardwood they had simply cut; it had never been in water. It wasn't natural aside from being wood. If you can send me a photo of the driftwood you're looking at, I can tell you what I think. My section on treating driftwood to leach out the tannins, lignins, and also disinfect is at http://www.fishpondinfo.com/plants/decor2.htm#drift As for being pre-treated to sink: I have bought many driftwood pieces over the years, many attached to slate by screws. I cannot remember a single one that didn't float initially except maybe a few tiny ones. I had to lay additional slate pieces on top of the other slate pieces to keep them down. My two big driftwood pieces would still float for years if I removed those extra pieces but do not any longer. They really need to attach them to larger slate pieces. I'm not sure what "pre-treatment" they've done to the wood they're advertizing that you saw. I don't think it's something harmful for your pleco though. |
