Fiji is hard to come by in my area, I'll have to get it online. Any suggestions on a good web site?

Just curious... why is 50#'s not enough? I have a 125g FO and don't have any LR in the tank... just a big wet / dry and a fuge..... I have a big bio load and all works out great with me.

Caige, what do you consider a large bioload? If you have enough sand/bioballs/filter media/sponges/decoration (basically anywhere the bacteria can live) the tank could support a larger bioload.....

sorry.. i just meant that my set up (actually friends set up, i'm currently on mine) has a lion fish, trigger, tangs, grouper and eel and he has no LR in the tank... he has a 40gallon wet dry that has about 5gal of bio balls... then another compartment that has about 5gal of LR rubble.... then goes to a fuge..... but in the tank he just has all the fake stuff --- which seems to be a big pain because every 2 weeks he takes them out and bleaches them.

I just bought a 125gal myself and only planned on having about 20#'s of LR in the actual tank... .and I was almost mimicking his setup under it ..... hope it works!

The Bio Balls are taking the place of the LR for the Bio filtration. With the FOWLR setup you use LR and you don't have any bio balls. I don't know the percentage of LR you have to have for FOWLR put it is recommended that you have 1-1.5 lbs of rock per gallon. Base rock will become live after a while.

It`s really somewhere around 1 to two lbs per gallon. Good explanation Bigmike. It really depends on the weight of the LR to figure out how much you need. The heavier the rock the more lbs you`ll need as the lighter the LR the less lbs you`ll need. Read this

I also want to add, LR is a good way to simulate their natural habitat, it helps to define territory and provides safety and a comfy spot to sleep and hide.
