| Re: Tufa's tank!!! Marco is dry (dead) Fiji rock. Because all the coralline has died, it is usually white. However, it happens to be the most porous and best looking rock I have seen to date. It is very lightweight when it ships, so the price is very nice as well. I kinda wish I had gone ALL Marco as I love it so much, but then my tank prolly would have taken 6 months to cycle! (Of course, one could always buy live sand) |
