Dennerle Crystal Quartz Gravel (5kg) Diamond Black
Dennerle crystal quartz gravel is a classic in the range – for many decades one of the best gravels you can use in your aquarium. The excellent appearance and perfect biological function of the Dennerle crystal quartz gravel, which does not harden the water, are probably unique in this combination.
Dennerle Crystal Quartz Diamond Black Gravel is lightfast and CO2 resistant, can be used again and again, and retains its color even after years. Due to the iron oxide coloring, the quartz gravel is water neutral and guaranteed free of pollutants. The grain size of 1–2 mm suits bottom-dwelling fish and reduces the risk of dirt in the gaps.
The fine quartz Dennerle gravel is also very suitable for plants with fine roots. The use of rounded grains greatly reduces the risk of aquarium animals injuring themselves. The very small gaps that nevertheless exist provide a perfect settlement area for important bacteria. Dennerle quartz gravel does not need to be pre-washed.
