Dennerle Crystal quartz gravel slate grey, 5 kg

Crystal Quartz Gravel for Freshwater Aquariums

Dennerle Quartz Gravel is a classic in the range and has been one of the best gravels to use in your aquarium for many decades. The excellent appearance and perfect biological function of this non-hardening gravel are truly unique in this combination. It is lightfast and CO2-resistant, can be reused repeatedly, and retains its color even after years. Due to the iron oxide coloring, the quartz gravel is water-neutral and guaranteed free of pollutants.

With a grain size of 1 – 2 mm, it is suitable for bottom-dwelling fish and reduces the risk of dirt accumulating in the gaps. It is also very well suited for plants with fine root systems. The use of rounded grains significantly reduces the risk of injury to the animals in the aquarium. The very small gaps that remain provide an ideal settlement area for important bacteria. Dennerle Quartz Gravel does not need to be pre-washed (except for the natural white color).
