FloraViv Blackwater is designed to simulate conditions of color and content of Amazon and similar forested river regions of South America, Southeast Asia and Africa. It is particularly useful as an aid to induce spawning and hatching of certain species of fishes native to those areas. It will tint the water a light yellow to a light brown color, depending on the amount used, reducing stress and improving color and vigor of fishes. FloraViv Blackwater contains naturally chelated iron, other minerals, and vitamins that will stimulate biological cycles in fishes and plants, without causing unsightly algae growth. FloraViv Blackwater contains no gluconates, or dangerous polycycloglutaracetal, or glutaraldehyde as some competing products do.
