Couple of quick notes: One noob to another.
*No one* that I can find aquacultures fiji rock. It is all taken from reefs. The main reason for this is that it doesn't make financial sense to do so - buying from south pacific islands is cheaper than if you made your own.
I bought 70lbs of tonga lalo premium rock from marinedepotlive 6 weeks ago. I assumed (as others do) that since L.A. is closer to Portland, I could get a fresher batch. I found out later that my rock sat on the beach for a couple of days in Tonga, then shipped to LA and sat in a warehouse for 24hrs then came to me overnight via FedEx. Time from the reef to my door was almost a week. I had *significant* die-off. My NH3
readings during my cycle were off the scale for 4 solid weeks.
The upside as fishfreek mentioned to FL rock (whether it is LR
.com or GulfView, etc..) is 2 fold - 1.) they grow it, less impact. 2.) it comes out of the keys into their tanks where it stays underwater until you order it. This is by far the freshest way to get rock into your tank from a retail vendor, even if you live in HI.
The upside to Fiji rock is looks (for some people) and lower density / more porous rock. If you really really dig the looks of the fiji rock, then I'd suggest buying dry/base rock from somewhere, save a few bucks and culture your own coraline, etc. over time.
