• 5kg Blue Treasure Coral Sand 0.5-2mm grain size
• Our 100% natural coral sand from Blue Treasure is ideal for marine aquariums. Coral sand will buffer the pH of the water to around 8.2, meaning it is ideal for marine aquariums and also African cichlid freshwater tanks due to these species preferring a higher pH water.
• Coral sand has a very high surface area, and is very porous, which allows beneficial bacteria to colonise and assist with the effective filtering of the aquarium water. This sand also has a rich calcium, carbonate and trace element composition.
