Product Information

Dennerle's range of Crystal Quartz Gravel is perfect for planted aquariums, as it provides a good base to support plant growth. Place a layer on top of an aquatic soil for healthy plants and a great looking tank.

This natural looking brown gravel is the perfect accompaniment to a planted aquarium, as it is light resistant and CO2 proof too. As the Crystal Quartz is hardener free too, it won't affect the delicate pH balance of your aquarium.

The rounded edges mean that the gravel is safe for all inhabitants, including bottom dwellers.

Use a fertiliser supplement regularly to ensure that the levels of essential trace elements are maintained for healthy plant growth. Yellowing or brown plants are a sign that the water is deficient of one or more elements, which must be replenished for beautiful, green plants.

Key Features:

  • Hardener-free
  • CO2-proof
  • Light-resistant
  • Water-neutral
  • Grain size 1-2mm
  • Rounded edges protect bottom-dwelling fish.
