Burgundy lava rock, 3/8 inch, washed and screened at the yard. The reddish color and smaller nominal grade offer a different appearance from black lava or a larger irregular pile. Choose between 1 lb and 5 lb bags after planning the intended material volume.
Color is a visual comparison, not a chemical approval. Geological oxidation can explain red tones in scoria generally, but it does not identify every mineral in this batch or establish equivalence with the black material. We are waiting for the actual water-chemistry confirmation and do not promise a particular pH effect.
A smaller screened grade can be considered for a permitted contained compartment after its actual openings and clearances are checked. Compare the retaining mesh with real fragments. Keep room to close and lift the basket rather than compressing material into every available corner. Follow the equipment maker's media instructions.
A humid enclosure's lower collection layer is a separate design from an animal-contact floor. It needs suitable material, an appropriate separator, and a route to observe and manage excess water. This product is not a complete drainage system, and Swift does not sell the mesh shown in the educational layer diagram.
Inspect rough surfaces and loose fragments wherever animals could reach them. Do not use the material as a default loose reptile floor or assume a screened diameter settles every physical risk. Rinse suitable dry stone to remove fines released during transport.
The calculator estimates mass from a provisional bulk density. Confirm the full bag combination and box plan before ordering. Wet and dry views are representative; actual photographs will replace them when available, without turning a visual reference into a composition claim.
