Seachem meridian aquarium substrate is a 9kg bag of premium calcium carbonate gravel specifically designed for marine reef and African cichlid aquariums that require alkaline water conditions and a natural-looking substrate. Meridian is composed of biogenic calcium carbonate collected from ocean sediments giving it a natural appearance and composition that closely mimics the substrate found on tropical reef flats and lagoon floors. The seachem meridian aquarium substrate provides both aesthetic beauty and functional water chemistry support by slowly buffering aquarium water to maintain the alkaline pH levels required by marine fish corals and African cichlid species. Unlike crushed coral substrates that can appear harsh and unnaturally white Meridian has a warm natural coloration with subtle variations in tone that create a more realistic and attractive aquascape. The calcium carbonate composition slowly dissolves in aquarium water releasing calcium ions and carbonate alkalinity that help maintain stable pH between 8.0 and 8.3 the ideal range for marine and reef aquariums. This buffering action reduces the frequency of manual alkalinity supplementation needed to maintain proper water chemistry. For African cichlid tanks particularly those housing species from Lakes Malawi and Tanganyika Meridian provides the alkaline substrate these fish need to display natural behaviors and vibrant coloration. The grain size is carefully selected to provide good water flow through the substrate bed while being large enough to resist compaction and anaerobic pocket formation. The 9kg bag provides adequate substrate for medium aquariums or supplemental substrate for larger systems. Meridian is pre-washed to minimize initial cloudiness when first added to the aquarium though a brief rinse before use is recommended. The substrate is biologically inert beyond its buffering properties and will not leach harmful substances. Available at TaraPet the UAE trusted online pet and aquarium store with free delivery.
