Its large surface area supports beneficial bacteria growth, enhancing tank cleanliness and ecosystem balance. The deep black color provides a stunning contrast to aquatic plants, elevating the visual appeal of any planted tank. Safe for all fish life stages except snails and bottom feeders, this substrate is easy to prepare with a simple rinse and is allergen-free. ## 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.
