Drs. Foster & Smith have two listed

"Select Premium Fiji Live Rock," 4 to 14 inches, covered with corralline algae - $120 for a 45 lb box, 90 lbs for $240

"Fiji Foundation Rock," 6 to 14 inches, not covered with corralline but still has all the bacteria and stuff - $60 for a 35 lb box, 140 lbs for $240

Which one should I go for? My set up is a 90-gal FOWLR, current filtration is 50 gal overflow/sump/fuge (all in one large rubbermaid). Probably keeping one clown trigger in there and try to grow him huge, aka overfeeding him all the time... He needs a lot of swimming space though, so is 140 lbs too much anyway?
 
With 140 pounds of live rock, the clown trigger will be fine, make lots of nooks and crannies for him. I dont buy into that coraline algea price. All you have to do is get the fiji with minimal coraline, use power compacts and add the reccomended amount of Kent Marine calcium additive and you will have your coraline algea within 2 months.
 
Make sure what ever rock you chose is really porus. It is better for filtration.
 
Thanks for your replies guys.

Do I need all 140 lbs though? It's a species tank (he's the only inhabitant) so I'd rather give him more swimming room than more filtration (the sump/fuge is sick, it's really all the filtration he needs... I just like live rock for the extra biodiversity and aquascaping).

Basically what I'm asking is. Will the tank be really crowded if I put 140 lbs in, as opposed to say, 105 lbs? Clown triggerfish are not shy at all so I'd like to give him a lot of room, which is more room to grow - especially since I plan on keeping him in the 90-gal for life, or at least the time I'll have him (if he does get too big I'll have to sell him back to the LFS).
 
i thought the same thing. i have 55lbs in my 47gallon tank and it really only takes up the back wall. its not as much as you think once you get it in there.
