Our Product

With several options available in the calcium carbonate world, only CaCO3 Aragonite Products, Inc. offers the purest and highest quality aragonite product available. Our product content can certify in the range of 94 to over 97% calcium carbonate content for the raw product. The calcium content can be slightly higher in processed material. What does this mean to you? It means you can use half the product you would normally use, and get twice the results. In other words, it takes nearly twice as much as our competitors’ product to deliver you our product’s content level and effectiveness. Additionally, because of the pure nature or our product, some of the other added benefits include:

* Cost Savings

* Greater Effectiveness

* Durability

* Reduced Emissions

* Higher Absorbability
