My question as well. I have used the dark colored cork tiles as a
background on the outside of the tank but never on the inside. I thought
the cork was stained a dark color because normal colored cork is a much
lighter color isn't it? Also, these "tiles" appear to be made of cork
pieces, roughly a centimeter in size, that are glued together and I don't
want any of this glue poisoning the water or causing the tiles to
disintegrate after a while under water. Apparently there is no problem with
these cork tiles? How long have they been submerged?
