Cedar vs cypress

Thanks to Olga for pointing out why cedar should not be used in an aquarium.
I don't have experience with cedar but I can say from experience that
cypress is an excellent source of driftwood. It is a natural bog or swamp
tree and thus resistant to rotting. It sinks readily and does not discolor
the water. I have a large piece that is arched with many gnarls and holes in
a 75 gal discus tank. It was expensive but one of the best investments I
ever made for a well planted tank. Cypress driftwood is difficult to find in
stores because their natural habitat makes finding them and collection
