Live sand is expensive, I don't want to spend more money than I need to, but I can not figure out how much sand I need for my 48" long with 18" width. Can someone with good math tell me how many lbs of sand do I need for my tank ?
Thanks for your help.

Volume = 48 * 18 *1
= 864 Cubic inchs
Wet sand has an approx density of 0.0694 lbs/in3 (Note this is just a google on wet sand density, I have no Idea what the actual caribsea live sand density would be but I could guess it would be in this ballpark)
Which makes approx 60 lbs.
But if you looking to save money why buy live sand... just buy sand.... it will become "live" in time.
