Formula For DSB

[wamp]

I have seen this posted. I will wirte it down this time. Can someone give me the formula on finding the Pounds of sand needed for a DSB.
Thanks...

Here is the one I use:
length x width x desired depth of DSB x .0579 = lbs sand needed

Using that formula, how deep will it be? Thanks

There's a caculator to figure that out for you on GARF.Org. It comes out to be a little less than NM Reef's formula. So, I don't know what's truely more accurate. I'd personally go with Reef's, because more sand than what's required for 4" dsb certainly won't hurt anything!
