CaribSea's pre-washed Super Naturals™ are designed with your success, and ease of use in mind. They have carefully selected different sizes and colours 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 this sand can be used for marine aquariums, keep in mind you will have to use standard buffers, to keep your alkalinity and pH up where they need to be.
An inert, synthetic substrate. Recommended for freshwater aquariums with external filtration. Very bold look. Do not use with undergravel filtration and avoid burrowing or bottom dwelling fish. Grain size 0.1 - 0.5 mm.
