Usage Tips

- 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.

Coverage will vary based on tank dimensions, desired substrate depth, and aquascaping style. A 15.4 lb bag is useful for small to medium planted aquariums, deeper planting areas, or accent sections in larger aquascapes.
For larger tanks or deeper substrate beds, multiple bags may be needed.
