Crystal Quartz Gravel for Freshwater Aquariums
Dennerle Quartz Gravel is an excellent aquarium gravel that has been popular for many years. It has a great look and perfect biological function, and it won’t harden the water.
The CO2-resistant and lightfast gravel retains its color even after years of use. It’s water-neutral and free of pollutants due to iron oxide coloring. The grain size of 1-2mm is perfect for bottom-dwelling fish and reduces dirt buildup. The fine quartz gravel also works well for plants with fine roots. The rounded grains reduce the risk of injury to aquarium animals, and the small gaps provide an ideal area for important bacteria. Pre-washing is not necessary, except for natural white.
Highlights:
- Natural look
- Free from harmful substances
- Protection for bottom-dwelling fish due to rounded edges ( grain size 1 – 2 mm )
- Light-resistant
- CO2resistant and hardness-neutral
