Live Sand question

[tara]

Does anyone have a formula for figuring out how much live sand you put in a tank?
I'm going to be ordering some and I don't know how much to get, I have a 55 Gal. tank with 65 Lbs. of LR, (I am removing my UGF, and CC)

Here it is:
Length of your tank x width of your tank x desired depth (in inches) of your sand bed x 0.0579 = # of pounds needed
Example: (My 40 gal breeder)
36 x 18 x 5" x 0.0579 = 187 (# of pounds of sand needed for a 5 inch deep sand bed.

I have a 46g and used 100lbs to get 4-5inc. You can estimate from this if you like.
