Our pre-washed Super Naturals™ are designed with your success, and ease of use in mind. Packaged in sizes that make sense, most types are available in both 20 and 50 pound bags. We have carefully selected different sizes and colors for you, to help you create a natural underwater environment. These inert products will not affect your pH or alkalinity, allowing you to adjust both of these important water quality parameters any way you wish. While these can be used for marine aquariums, keep in mind you will have to use standard buffers, our aragaMilk™, or aragaMight™ to keep your alkalinity and pH up where they need to be.

Marine Sand - An inert, natural substrate. Recommended for freshwater aquariums with external filtration. Very striking. Do not use with undergravel filtration. Grain Size 0.1 - 0.3 mm.

Manufacturer Info

At CaribSea we take aquariums seriously. Since 1972 we have supplied hundreds of public aquariums, zoos, aquaculture facilities, public and private institutions, and hundreds of thousands of dedicated aquarists with the highest quality marine and freshwater products. CaribSea has been in the forefront of the principle that substrates are a piece of equirment, not just a decorative afterthought. Caribsea substrates are as precisely engineered as any piece of advanced equipment used by today`s hobbyists and professionals. CaribSea products are the chemical support, biological filtration, and biodiversity backbone for many of the most spectacular aquatic displays ever created. We are now celebrating our 35th year in the business, and our product line has continued to grow; making CaribSea your aragonite source and so much more.
