OF® 3DM Bacto-Sand is a revolutionary man-made “sand” that functions as a beneficial bacteria sand-bed, allowing you to create a beautiful natural environment for your fishes while keeping your water clean! The macro-porous structure greatly boosts the beneficial bacteria population and increases the rate at which harmful toxins like Ammonia and Nitrite are broken down. Crafted entirely using advanced manufacturing technology, Bacto-Sand’s rounded surface encourages water flow which prevents the build-up of harmful toxins in the sand-bed. Its rounded surface also makes it safe for the barbels of bottom-feeders like Corydoras, loaches, etc. This sterilized and pH-neutral sand does not contain any impurities, making it 100% safe and 100% ready to use. What are the advantages of OF® 3DM BACTO-SAND? • Reduces Ammonia and Nitrite.
