Sensei Stone is a unique variation of natural Magura sandstone, closely related to Blue Fin stone (both from the same geological group). While Blue Fin typically comes in flatter, slate-like pieces, Sensei Stone is known for its three-dimensional form and striking reddish hue.

This stone is neutral in terms of KH parameters, making it ideal for aquascapes. It promotes plant growth on its surfaces and provides beneficial habitats for invertebrates.
