i belive its 1 to 1 and a half pounds per gallon ( not really sure in liters though )

 

[S.Reef]

for biological purposes around 40lbs. Youll definatly want more for aquascaping.

how much do you have now?

 

[yamahaguy06]

around 25-30 pounds..

it kind of depends...your 20-30 pounds is probably actually just fine if it is low density and you plan to keep a pretty low bioload...we tend to over rock our tanks

i have a 90 gal tank 350l im looking at proberly 40lbs 20kg for starters. 10 normal base stuff and 10 realy nice stuff to keep cost down. then ill add as i need
.

sound ok.

cheers aron.

in my opinion it would be in your best interest to spend the extra money and get all of it the good stuff...

agreed and for a 90 gallon you will end up wanting to buy probably 100 lbs atleast, and if you buy all 100lbs you can get the cost down significantly, as apposed to buying like 10 lbs at a time 100lbs would be much cheaper in the long run

 

[1979camaro]

^ true. im not sure what mail order options you have in australia, but usually places will sell it by the box at a significantly cheaper price (closer to wholesale)

Ha Camaro, is more rock bad? I mean will to much rock harm something. and you need like 100 lbs for a 90 huh? I wonder what you need for a 180? 200lbs? that is a lot of $$. I think I might get a little more LR, just cuz I like the look of more. After importent stuff though.

And I would buy in bulk for shure, you can find some good LR deals online!

For a start know that all this lbs per gallon business is driven by how dense the stuff is, but as you are unlikely to see Tampa Bay brickrock in Aus you will likely be going with about 1 kilo per 10 litres. Too much doesn't hurt till you have no swimming space.
And try to keep the structure fairly airy as that helps a lot too.

thanks everyone. your help is appreciated. ill search around for mailorder

I wasnt saying a pund per gallon thing it is usually just what looks aestitically correct to you, for me I have about 140 lbs in my 90 gallon and 75 lbs in my 40 gallon, just a personal preference though
