Hi DeltecRules,
That is very common for Fiji. We basically have two different types of Fiji available to us.
The first one being a really nice coralline colored up rock, that is essentially round with no little caves, fingers, nooks, crannies, etc. This is also pretty dense stuff.
The second type of Fiji available to us what you received. This Fiji doesn't have a whole lot of coloration to it, however the shapes and density of the rock are excellent, almost rivaling that of Marshall Island in some cases.
We push this type of rock because we feel it is much more important to have a good base of life and excellent shapes, as well as surface area, than what it is to have the coloration. The color will always come (typically within a matter of just a few weeks you will start seeing a difference), so it's very important to pick out the shapes and rock with a lot of surface are for maximum biological filtration.
Keep in mind too that we tank every bit of our rock in water. When you see a lot of people who receive a box of rock that is just bursting with coloration this is rock that has been setting in a box since it was pulled out of the ocean. You can keep coralline algae on rock that is just pulled out of the ocean and set dry for about 3-4 weeks without it changing much in appearance at all, however once you put that back in the water it will bleach white on you. Our rock hits the pools about 36 - 48hrs after it has been pulled from the ocean. When it hits our water we do get some dieoff of coralline algae, which is unavoidable, however the macro and micro life in and on the rock survive just fine and repopulate itself very quickly by doing this.
If you have any questions please feel free to let us know. I really like the pieces you received as well, almost doesn't even look like Fiji! Now once it gets some color back in your system I'm sure you'll be extremely happy with it!
