lbs of live rock per gallon?

[kindaobsessed]

wondering what the ratio is for amount of live rock per gallon. have heard 1 lb. per 10 gallons, 1 lb. per 5 gallons...etc. please clue me in. also, is it cost worthy to mix live rock with regular rock (which will seed eventually i guess) and live and non-live sand to save money. many thanks in advance.

If it's gonna be your primary bio-filtration, so i would use 1-1.5lbs/gal minimum.

1 to 1.5/lbs per gal is the usual and it is cost saving to mix live and non-live together which will eventually grow because of the live stuff.

is the ratio of 1-1.5lbs per gallon also pertain to the depth of a dsb? i've read that 3-4 inch dsb is a desirable depth. again, thank you for the replies. this is a great site and i've turned many people on to it

Use this to calculate the amount of sand:
length x width x desired depth of sand bed x .0579 = lbs of sand needed(all measurements are in inches
