Yes. Our eco-live-rocks are made with some concrete (aprox 30%) ... However, most of the raw material is calcium carbonate (aragonite sand, coral fragments, shell bits of oysters, mussels, scallops and snails).
The concrete used in the mixture is fully reacted. These rocks are fully "kured"... That is, the by-product of the hardening reaction of concrete (calcium hydroxide), already leached out of the rocks. Our eco-live-rock are 100% tank-safe.
