Seachem Replenish

Introduction

Seachem Replenish is a proprietary blend of salts designed to restore essential minerals removed by reverse osmosis (RO) or deionized (DI) filtration. It safely restores General Hardness (GH) using a balanced combination of soft salts (sodium, potassium) and hard salts (calcium, magnesium), creating a stable and biologically appropriate freshwater environment. Maintaining proper mineral content is critical for fish health. A lack of minerals can cause osmotic stress, and in severe cases, osmotic shock, which may lead to rapid fish loss. Replenish helps prevent these risks by recreating a properly mineralized aquatic environment.
