## Overview

AquaNatural Diamond Black is a premium 10lb natural quartz gravel substrate (2-4mm) designed to enhance aquarium aesthetics with its sparkling black finish. Its large surface area promotes beneficial bacteria growth, supporting a healthy aquatic environment, while providing an ideal contrast for planted tanks. Safe for most fish and plants, this substrate is easy to rinse and maintain, making it a top choice for discerning aquarium enthusiasts.

## Description

Product Description Quartz Gravel is the Rolls-Royce of our range. Natural Quartz not only looks wonderful but has also been shown to help reduce the build up in the aquarium. This is partly due to the huge surface area of quartz which offers added space for the establishment of tank cleaning bacteria. Quartz sparkles underwater due to the many light reflecting facets and is a striking substrate that contrasts well with aquarium plants such as anubias and desertcart swords. Directions Rinse until water runs clear, place in base of aquarium. Not reccommended for snails or bottom feeders.

Review: 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.
Review: 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

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.
