CaribSea Super Naturals Crystal River Freshwater Sand, 20-lb bag

Re-create the natural world of your finned friends with CaribSea Super Naturals Crystal River Freshwater Sand. This beautiful, natural uncoated river substrate offers a finer grade of natural sand, packed with living, water-purifying bacteria, state-of-the-art clarifier and a complete water conditioner. With Crystal River, all you need is tap water to get started, plus sand-size grains are friendlier to bottom dwellers. The approximately 0.5-1.0 mm grain-size immediately begins the cycling process, eliminating new tank syndrome and discouraging nuisance algae. The freshwater sand is great for detoxifying metals, eliminating ammonia, neutralizing chlorine and chloramines, plus it provides a protective slime coat for stressed fish and reduces nitrates and nitrites. This is also great for use with aquatic turtles, terrestrial turtles, tortoises, aquatic amphibians, and invertebrates.
