CaribSea Tahitian Moon Black Sand (20 lb), Our pre-washed Super Naturals are designedwith your success and ease of use in mind. Packaged in sizes that make sense. The inert product will not affect your pH or alkalinity, allowing you to adjust both of these important water quality parameters any way you wish. To be used in marine aquariums, keep in mind you will have to use aragaMilk, or aragaMight to keep your alkalinity and pH up where they need to be!
All Super Natural gravels and sands are pre rinsed but it will be useful to wet and minimally rinse all of them. Then place in aquarium and add water, (it may be useful to use the empty substrate bag or a plate to disperse water and minimize churning the substrate).
