			 Hi, 
		
	
		
		
		
		
		
	
		
		
	
	
	The density is about the same as regular calcium carbonate sand (i.e. Southdown playsand). So, you can use this calculator as a reference. http://www.reefcentral.com/calc/SandBed.htm - Victor.  |

			 that one doesent work  [img]images/smiles/icon_smile.gif[/img] I get taken to the RC home page every time I click "calcuate" I did figure it out though.  a 3 foot x 2 foot tank has a bottom of 6 sq feet. if I want 6" bed then one cu foot of lime will cover 2 sq feet and if 90 lbs is 1 cu ft I need 270 lbs to cover 6 sq feet 6" deep  [img]images/smiles/icon_smile.gif[/img]
