CaribSea' s African Cichlid substrates can help recreate a variety of environments. Rift Lake Authentic is a typical Mbuna setup while Sahara Sand is ideal for nesting feather fins. The original African Cichlid Mix is great in just about any application! The bold colors of all the Cichlid Mixes encourage the vibrant natural coloration of your fish. CaribSea' s Cichlid products naturally buffer for the life of the aquarium simplifying the process of matching water quality parameters to the Great Rift Lakes of Africa. African Cichlid Mixes also resist the downward drift of pH in long established or crowded systems. Seasoned hobbyists appreciate the ease of maintaining water quality as much as the beauty of these substrates.
