Plant Benefits
CaribSea Peace River provides a stable substrate base for rooted aquarium plants. While it does not contain added plant nutrients, its small smooth grain size helps 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
One 5 lb bag can provide roughly a 1-inch substrate depth in many 5 gallon aquariums, depending on tank footprint and aquascaping layout. It can also be used for accenting, layering, or creating natural riverbed sections in larger aquariums.
For larger tanks or deeper substrate beds, multiple bags may be needed.
Setup Tips
- Although pre-rinsed, a light rinse before use can help reduce fine dust and 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.
