Usage Tips

  • Rinse thoroughly before use to help reduce dust and initial cloudiness.
  • Add water slowly over a plate, bowl, or plastic bag to avoid disturbing the substrate.
  • Use a deeper layer in areas where heavy planting is planned.
  • Pair with root tabs or liquid fertilizers for nutrient-demanding plants.
  • Allow filtration to clear any remaining fine particles after setup.
