Live rock!

[KNJ]

Hey all, can't work out how much live rock I need as all info is in gallons/lbs and I use litres/kgs and am terrible at math.
I have a 450L tank.
Thanks if you can help

According to Google 450 liters is 118 gallons so you probably have 120 gallon tank equals 120 pounds

Which equals 55 kgs according to Google. Lol

You're the best thanks, I don't know how but I got 550kg and was so confused

that is just a rule of thumb, not necessary what you need to put in there. Just put in as much as you feel like and how you'll like your tank to look. I have a 70g and I put under 20lbs of dry rock in there because I like that open look.

I agree that you don't need 1-1 gallon to pound of rock, make something that you like with a rock structure, and you'll be good It goes more about surface area than pounds. I have under 100 in my 180, and less in my 120. All my fish and corals are happy.

Build a scape that you like and that works for your tank, if you use less rock in the display you can add rock to a sump or just maintain a lighter bioload!
