About CaribSea Live Products
When setting up an aquarium with CaribSea`s live products please do not rinse the substrate! The susbtrate should be carefully placed on the bottom of the aquarium, and your preconditioned water should be added carefully. Cloudiness will be greatly reduced if a plate or empty bag is used to stop the water being added from disturbing the substrate underneath.
