{"product_id":"pr-calcium-sand-blue-5kg","title":"ProRep Calcium Sand Blue 5kg | Arid Reptile Vivarium Substrate","description":"\u003cp\u003ePR Calcium Sand Blue is a coloured calcium-based loose substrate designed for reptiles from arid and desert environments. Made from pure natural limestone, it serves a dual purpose: providing a naturalistic vivarium floor covering while also acting as a supplementary calcium source if ingested — making it a more considered choice than many inert sand alternatives.\u003c\/p\u003e\u003ch3\u003eSubstrate Composition\u003c\/h3\u003e\u003cp\u003eFormulated from natural limestone, PR Calcium Sand Blue is unlikely to cause gut impaction if consumed in small quantities, unlike silica-based sands. This makes it a practical option for desert-dwelling species that naturally ingest substrate while feeding.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eSpread evenly across the base of the enclosure to a depth of at least 2.5–5cm (1–2 inches). A small section of the substrate can be lightly misted to create a localised humidity gradient within the vivarium without saturating the overall layer.\u003c\/p\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSpot-clean daily to remove waste and soiled material\u003c\/li\u003e\n\u003cli\u003eFull replacement recommended every two to three weeks, or sooner if the substrate becomes heavily soiled or wet\u003c\/li\u003e\n\u003cli\u003eAvoid allowing the substrate to become saturated — excess moisture compromises hygiene and substrate integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHeat Source Compatibility\u003c\/h3\u003e\u003cp\u003eIf using an under-tank heat mat as your primary heat source, keep the substrate layer shallow. A thick layer of loose substrate over a heat mat can restrict heat dissipation and cause the mat to overheat.\u003c\/p\u003e\u003cp\u003eAt 5kg, this bag provides enough substrate to set up or fully refresh a standard desert vivarium. The blue colouration suits naturalistic or stylised arid builds alike, while the limestone base means it earns its place functionally as well as aesthetically.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54148627693905,"sku":"SPC102","price":9.59,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/SPC102_1.jpg?v=1782600018","url":"https:\/\/viperia.co.uk\/products\/pr-calcium-sand-blue-5kg","provider":"Viperia UK","version":"1.0","type":"link"}
