Description
Overview
Seachem Replenish™ is a proprietary blend of salts designed to restore physiologically relevant minerals removed by reverse osmosis (RO) or deionizing (DI) filtration. It restores General Hardness (GH) using a balanced combination of “soft” salts (sodium, potassium) and “hard” salts (calcium, magnesium).
Restoring minerals is essential for species whose osmoregulation depends on mineralized water. Without proper GH, fish and invertebrates can experience osmotic stress or osmotic shock, which can be fatal. For planted aquariums, Seachem Equilibrium™ is recommended to complement Replenish™.

GH Reference Chart
| meq/L | Rating |
|---|---|
| 0–1 | Soft |
| 1–2 | Moderately Soft |
| 2–3 | Slightly Hard |
| 3–4 | Moderately Hard |
| 4–6 | Hard |
| 6+ | Very Hard |
Directions / Usage
- Add 5 mL (1 capful) of Replenish™ to 40 L (10 US gallons) of water to raise GH by 1 meq/L (2.8 dGH).
- Recommended GH restoration into DI or RO water: 1–2 meq/L, which equals 5 mL per 20–40 L (5–10 US gallons).
