Blackwood creates amazing scapes and gives natural feel to any aquarium. It will sink fast and will not discolor the water.
This is not the"piece" of Blackwood that I purchased, but since each piece is unique, I am only able to write a review for one that is currently on sale. I took a leap of faith purchasing a piece of wood for $49.95 and I am sooo glad that I did; I literally said "Oh my 'gosh'!" when I pulled it out of the box. The the color of the wood is striking, with streaks of reddish-brown throughout. It's a hefty pice of wood-feels weighty in the hand-yet it will still rise to the top of the tank if it's not weighted down/secured. The piece that I purchased transformed my tank from looking average to one that would make anyone say, "Ahhh...!"
