I recently bought a nice piece of driftwood at my local LFS with the intention to start up a South American apistos tank. I have changed my mind however, and I would like to start up a tank for the Tanganyika cichlids. I can't return the driftwood, and all my other tanks have no room. The driftwood is soaked and boiled, and no tannins are left. My question is: would driftwood in a Tanganyikan tank work? I understand it may soften the water but I plan to use crushed coral as the substrate. Don't blame me for impulse buying the driftwood, it was on sale for $1.50 per pound.
