"Real Reef Rock" is great. I've been buying it for the past 6 months and love it. Totally eco friendly man made stuff with pigment in it to make it look like it's covered in coralline. Fantastic stuff. One thing to note, the price differences between retailers of it are incredible. I've seen it for as much as $10.99 a pound.....almost pissed myself laughing. It can be found for $5.99 a pound, so it is worth shopping around to get more for your money. Beautiful stuff.
where's me money
