Was it soaked or boiled previously? If not, it is probably leeching tannins. They are completely harmless to fish and plants, and will dissipate in time depending upon the age of the wood and any prior soaking.
From your photos and details int his thread, this is my take on the reddish tint. I've had it from wood many times.
I do like your aquascape, as I've mentioned. Very nice, it makes the tank look larger.
I do have another substrate under the black sand, I used First Layer Pure Laterite for planted aquariums. and i didn't have enough so i put the black sand over, more estically pleasing as well. the drift wood is on the small size, about the size of my hand, i have small hands.
as for the fish, i think i'll be putting a betta in the tank...just not till i figure out this water thing.
