Blue Treasure Coral Sand comes from the pollution-free island in the South Seas of China. No phosphate, nitrate and surface contaminants and you can see that immediately when you open the bag of sand. Beautifully clean, white coral sand! More beautiful than anything else on the market!

Coral sand is naturally very porous, it is therefore suitable as a bottom sand filter in aquarium tanks because of the large surface where useful bacteria grow and therefore contributes to a stable biological balance.

The sea beach is brought Blue Treasure Coral Sand to your living room!

The main content of the coral sand is calcium carbonate, which can be beneficial for the stability of the pH value in seawater.
