live rock water displacement

[steven1]

how much water is displaced with 75lb of live rock

 

[nycbob]

hard to say since all live rocks r different. some r porous and some r more compact. 75 lbs is probaly 15-20 gallon of water?

What are the dimensions of the tank? How much live sand do you have?? I have a reef calculator

my dimentions are 48L 18W 21H with 80lb of sand
