Aqua Natural Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 1-2mm

The sand absolutely sparkles in light. It looks great in a fish tank. It’s currently sitting in a 10 gallon tank. When you first pour it in it does get the water a little cloudy but with any good filter it clears up very quickly. I absolutely recommend it for anyone.

En mi caso fue una excelente opción para mi gambario, les recomiendo leer las instrucciones de uso para su correcto funcionamiento, ya que veo mucho comentarios negativos. Lo recomiendo ampliamente si su intención es tener gambas, platas o peces pequeños.

Let's say I love the look of sand but I hate how much you have to wash it.. This is a sand like substrate, but it's quartz.. I did give it a small rinse, because I always just rinse my substrate before it goes into my tank.. Now, I stuck the entire bag in a 75 gallon. I'm about to fill that tank. You would probably need 2 bags. I mixed this with a different substrate.

Not suitable for bottom dwellers. Extremely sharp, I even cut my hand while rinsing! Some pieces are long, thin. It’s also not even black - it’s about 50% green, with occasional earth-tone pieces. Wish I’d trusted the forums and steered away, but I was eager for a black sand-like substrate. I’ll go back to using enamel-coated silicon sand for now. All grains you see in the photos are from the bag I ordered. Photos taken outside in the shade (natural light). Would return but I left it too long. Might use for my shrimp instead, after more research.

Love this sand. Much better option than the painted rocks. It’s more natural . My betta Tobias likes it,just waiting for his plants and his tank will be complete
