Liquid Amazon Blackwater Solution by Caribsea helps you recreate natural tropical environments in your freshwater aquarium. Natural tannins within the solution replicate the ideal characteristics and conditions of the world's tropical waters, created by slowing decaying vegetation such as leaves, peats, and soils. This process mimics the essential elements of native blackwater environments, such as the deep jungle Amazon, the Congo River, the Indian Subcontinent, Indonesia (including Borneo), and brackish tide pools and creeks located in the southern United States. Because it imitates the conditions of these locales so well, Liquid Amazon is perfect for aquariums featuring inhabitants such as discus, bettas, tetras, corys, angelfish, gouramis, arowanas, barbs, and freshwater shrimp. Bring the jungle right to your aquarium and keep your habitat happy and healthy with CaribSea's Liquid Amazon!
