Replenish (500ml)

Seachem's Replenish (500ml) is a proprietary blend of salts designed to replenish physiologically relevant minerals that are removed by reverse osmosis or deionizing filtration. It restores GH using a balanced blend of both "soft" (sodium, potassium) and "hard" (calcium, magnesium) salts. Restoration of mineral content is essential since a complete lack of minerals will result in osmotic stress in species whose osmoregulation systems are adapted to a mineralized environment. Science!
