This Sand Bed Calculator is designed to help determine the amount of aragonite substrate needed for your tank. Just enter the length, width, and depth of sand desired and the calculator will display the amount of aragonite needed. Garf recommends the use of a plenum covered with 4 inches of CaribSea Seaflor Special Grade Reef Sand.
The calculator bases the weight of the aragonite sand on Carib-Sea's estimate of 70 lbs. per Cubic foot.
