Calcium Sand Substrate for Reptiles 25kg | Vivarium Sand

A 25kg bag of calcium-based sand substrate, suitable for arid and desert vivarium setups housing reptiles that thrive on loose particle flooring. Calcium sand is a popular choice for keepers of species native to dry, sandy environments, offering a naturalistic look while providing a substrate that supports digging and burrowing behaviour.

What It Is

This substrate is composed of calcium-based sand particles, designed to replicate the dry, fine-grained terrain found in desert and semi-arid habitats. It is suitable for use in terrariums and vivariums housing lizards, tortoises, and other arid-dwelling reptiles. The 25kg bag is suited to larger enclosures or keepers who maintain multiple setups.

Vivarium Use

Calcium sand can be laid to a depth that allows surface-dwelling species to move naturally across the substrate, and provides enough depth for burrowing species to dig. It is compatible with the temperature gradients typical of desert vivarium setups, including under-tank heating and overhead basking lamps.

Things to Consider

Loose particle substrates including calcium sand are best suited to adult reptiles. Keepers should research the specific requirements of their species before use, as substrate suitability varies. Spot-cleaning regularly and replacing the full substrate periodically will help maintain a hygienic environment.

At 25kg, this bag offers a practical quantity for setting up or refreshing a full desert vivarium without repeated restocking.
