## Long description

Crushed Red Tumbled Stones from NB Minerals are natural decorative aggregate with a grain size of 30–50 mm, supplied in a 10 kg package for use in aquariums and terrariums. These tumbled stones provide a uniform rounded appearance and a vivid red color that can be used as substrate accents, surface decoration, or drainage layers. The product is sold as natural stone; users should inspect and rinse the material prior to placement to remove surface dust and fine particles. Chemical composition is not specified, so compatibility checks with sensitive aquatic or terrestrial species and water parameters are advised before use.
Advantages
These red tumbled stones offer visual consistency and a polished texture from mechanical tumbling that reduces sharp edges. The 30–50 mm grain size makes them large enough to create stable decorative layers and effective drainage zones while small enough for flexible arrangement in aquarium and terrarium layouts. Supplied in a 10 kg pack, the stones are ready for multiple uses in hobby projects and landscaping details once cleaned. Their natural mineral origin provides durable, long-lasting decorative material for indoor environments.
Suitable for
 Accent substrate and decorative top layers in freshwater and planted aquariums (after compatibility checks)
 Terrarium floor coverings and surface visual accents for reptiles and amphibians
 Drainage layers beneath soil or growing media to improve water distribution
 Anchoring larger plants or hardscape elements within terrarium or paludarium layouts
 Small-scale landscaping, craft projects, and decorative containers
Key specifications
 Grain size: 30–50 mm
 Finish: Tumbled / rounded edges
 Color: natural red tones
 Quantity: 10 kg package
 Use: suitable for aquarium and terrarium decorative and functional applications
How to use
Before placing the stones into an aquarium or terrarium, sort the material to remove any oversized fragments or fines and rinse thoroughly under running water until the rinse water runs clear. For aquatic use, perform a small compatibility test: place a few stones in a jar of tank water and monitor for changes in pH, hardness, or turbidity over 24–48 hours. Arrange the stones manually to create the desired surface or drainage profile; for drainage, place a single layer beneath substrate, and for decorative accents distribute stones on top of the substrate. Do not rely on these stones as the sole filtration medium in aquariums.
Usage recommendations
Inspect and rinse all stones before use. For aquatic systems with sensitive species or precise water chemistry requirements, consult water parameter testing and perform gradual introduction. Avoid using stones treated with sealants or coatings unless explicitly identified as aquarium-safe.
