Plant Benefits
CaribSea Crystal River provides a stable substrate base for rooted aquarium plants. While it does not contain added plant nutrients, its grain size can help plants anchor in freshwater aquascapes.
For heavy root-feeding plants such as swords, crypts, and vallisneria, pair this substrate with root tabs or a nutrient-rich base layer for best results.
Coverage Guide
A 20 lb bag is useful for medium aquariums, planted layouts, shallow substrate beds, accent areas, or layering in larger aquascapes. Actual coverage depends on tank footprint, desired substrate depth, hardscape placement, and aquascaping style.
For larger aquariums, deeper beds, or heavily planted layouts, multiple bags may be needed.
Setup Tips
- Rinse before use to help remove loose dust and reduce initial cloudiness.
- Add substrate before filling the aquarium with water.
- Pour water slowly over a plate, bowl, or plastic bag to avoid disturbing the substrate bed.
- Use root tabs for heavy root-feeding plants.
- Vacuum lightly during maintenance to avoid disturbing plant roots or aquascape layers.
