Mark,
thanks for your help. I am thinking of adding the following to the new
60x24 tank. It will be ~300Lbs of sand giving me a 4" DSB.

1) Is the sand good?
2) is 4" enough for a DSB?

5 x CaribSea Aragamax Sugar-Sized Sand 30 lb (CaribSea Aragamax Oolitic
Select Reef Sand)

5 x CaribSea Aragamax Oolitic Select Sand 30 lb (CaribSea Aragamax Grand
Bahama Reef Sand)

Thanks for the feedback!
