AquaNatural Diamond Black 10lb, Premium Gravel and Substrate for Aquariums, Fish Tanks and terrariums, 2-4mm

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.

I really like it aesthetically as it blends with a lot of things, especially with water with tannins. It is also clean and easy to maintain than other substrates.

Perfect consistency for Cory’s slight coarser than a true sand but close. Color is a true black with “sparkling “ crystal dispersed throughout. I did need to rinse before adding to aquarium but I did so about 3lbs at a time. And after only a few minutes was able to add to an existing aquarium by using a solo cup to transport it to the bottom and spread it out over my existing gravel with no noticeable change in water clarity. Yes a few stray grains floated around for a few hours but the water remained clear and I was never concerned about harm to the fish. In the end does what it’s supposed to do at reasonable price and looks good doing it

Great looking sand, it's as mentioned in the description! We'll see how well my plants do in this substrate compred to my other one!!

I really like the way this looks in my tank. It becomes almost a canvas for beautiful underwater inhabitants and the decor you choose. However, because this substrate is so fine there is a lot of dust that needs to be rinsed off. Sounds easy, but it isn't. You will want to put the hose nozzle under the sand, run water on low and let the bucket overflow a few times, helping the layers of dust flow out. JThen once you put the substrate in the tank you will still get quite the cloud when water is added.
