  • Key Points

  • Characteristics

  • Usage

  • It can be used in both aquatic and terrarium environments.
  • Rinse rocks and stones with water before use. Use a brush to clean it before introducing the stones in the aquarium.
  • Avoid placing rocks directly on the glass as they can be very heavy and sharp. Instead, place substrate or our LandForms before placing the hardscape to help fix the exact stone position with more freedom.
  • Always secure the stones, especially when placing one rock on top of another, you can do so with our ScapeBound, as the top rock may move or fall during regular maintenance, harming your dwellers or even breaking the aquarium.
  • Position stones a few centimeters/inches away from aquarium glass walls to facilitate maintenance.
  • Control any alterations in pH and kH by regular water changes with osmotic or soft water, or by using a water softener if necessary.
  • Safe for fish, shrimps, and other aquatic animals
