Okay this may sound silly. How many pounds of sand do I need to create a 3-4" dsb in a 75G tank that is 48" long by 18" wide? and is 3-4" of sand enough to create a good working dsb? :Angel:
Okay according to reef central I will need 150 lbs, I will be getting 75 lbs of live sand and the other 75 lbs I will use play sand? which goes down first the play sand with the live sand on top?
