At whitecorals.com you can choose: Fresh live rock "Out-Of-The-Box" will be shipped shortly after import. These stones are normally strongly overgrown with macroalgae of all kinds. Fresh live rock is particularly suitable for new tanks. To maintain the quality, the stones are freed from organic growth and sediments 2-3 days after import. This is necessary in order to promote the inner biology of the stones and promote micro-organisms, so the so-called conditioned stones have significantly less growth and are particularly suitable for running tanks. We would be pleased to fulfill your wishes!
