Yes, I would recommend this.


Pros: lots of rubble!

Cons: none that i can think of

Great for super gluing corals to it... I let it encrust on it..then I glue the rock rubble onto my main live rock piece.. it holds up great. I like the porosity it gives to the corals seem to enjoy attaching to it and encrusts on it. It's a calcium carbonate base so it makes sense

No, I would not recommend this.

product shipped is not as advertised

Pros: it IS CaCO3, true. And white in color.

Cons: it is NOT coral rubble

the phot clearly shows coral rubble. What was shipped is not coral rubble. Its either artifical rock manufactured from aragonite sand, or some kind of mined limestone product.

Its like showing a clownfish and delivering a goldfish - yeah theyre both orange fish but not interchangable

Its a shame, this product USED to be as advertised here, but I guess the manufacturer changed their source
