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.
