Elephant Skin Stone is a greyish rugged rock that steps up the flamboyance of an aquarium.  

Key Features:

• Elephant Skin Stone is a sedimentary rock composed of mostly calcium magnesium carbonate and is commonly called Dolomite Rock, Dolomitic Limestone, and Dolostone. 
• It is very heavy and comes in various shades of gray or reddish-brown, the Oxidized iron and magnesium make the rock appear browner or reddish-brown.
• It increases the pH of water making it alkaline.
• It has a unique texture as it is got by years of weathering and natural erosion, giving it a leathered, wrinkled appearance. Having said that, Elephant Skin stone is the best-textured rock used in aquascaping.
• It is a hands-down choice by aquascapers, as it makes amazing background scapes and centerpieces.
