The Brightwell Aquatics KoraLagoon Substrate is a high-purity aragonite blend designed to mimic the natural substrate found in tropical reef lagoons. This product encourages biochemical reactions within the sediment, which facilitate the continuous release of essential ions such as calcium, carbonate, strontium, magnesium, potassium, and over sixty minor and trace elements. These ions are crucial for the growth of coral and other reef-building organisms while also stabilizing water pH levels. The substrate is composed of multiple particulate grades that cater to various needs, from refugia systems to sea grass beds and macroalgae tanks, making it highly versatile for all sizes of saltwater aquariums, especially nano-reef setups.
