Too big to boil. a foot and a half long or so. One of them has two five inch branches that come up off of it and the other is a wide and rounded at the bottom and pointed at the top. I did boil water and poured it over the wood but that was months ago when I just ended up getting tired of waiting and stacking rocks atop the wood until I made it stay down. A friend suggested I drill holes into the side of the wood I would like to lay against the substrate and simply fill the holes with lead (Using the same stuff you make sinkers with as a kid) as in most situations it will not react with water. Tying the wood down to a rock is not a suitable option for me either as the shape would make the fishing line a s hazard to my fish.
So, I am left wondering what type of wood this is anyway.
They are beautiful pieces I found them along a small stream nearby. They are gorgeous very dark intense red, and definitely not a soft wood of any kind. Do you think it is safe for me to artificially sink it as instructed I really would like these to be featured in the tank.
