BRStv Investigates - How Reliable Are Sand Bed Calculators?

Randy continues his sand study on this weeks BRStv Investigates by looking at sand bed calculators. Reef tank sand comes both wet or dry and also in a variety of grain sizes, all of which will affect the exact weight you need to purchase to accomplish a specific sand bed depth. Randy takes our most popular Caribsea sand options and weighs them out based on a 1" sand bed to see exactly how reliable the sand bed calculators are.
