DSB grain size and distribution
DSB grain size and distribution
Hi,
Can someone help me on my confusion with sand grain size in a DSB? Mostly what I read in the forums is the DSB should be a large % (85) "sugar" size aragonite sand, which I think is 0.5mm, the balance at 1-2mm. However Inland Aquatics, where I'm getting a microculture and detrivore kit recommends this:
At least I lb. * of Aragonitic substrate per gallon, consisting of the following:
* 15% Live Oolitic Aragonite Sand to seed the bed
* 45% Dry Oolitic Aragonite Sand
* 25% CaribSea Reef Sand
* 15% CaribSea Aruba Shell
Is the 45% Oolitic Aragonite 0.5mm?
Also, is there a way to calculate how many lbs of sand I need to get a 4" bed, based on sq. ft. of bottom surface area?
Thanks in advance for any help on this
