Another sand question

[fishman]

Im setting up a 100 gallon reef tank. I have 100 lbs of Southdown/Old castle (one of the 2) and 60 lbs of LS...Do I need to put aragonite sand in there as well? Also is 160 lbs of sand to much? What ratio should I have as far as playsand to LS or aragonite??
Thanks

southdown/old castle (if you bought the right one) ARE aragonite sand.

How deep is your sand bed? depth is more important than pounds (of course they're directly related, but not obviously so for someone with a different size tank)

I dont know how many inches it is..I dont know that i want a deep sand bed per say but would like to end up with about 2-3 inches. And yes I have the old castle I think...My tank is 5 ft long so I dont know how far 100 lbs of playsand and 60 lbs of LS will go...

Use the sand depth calculator to figure out how many pounds of sand you need.
