Seachem Replenish
Seachem Replenish is a mineral water conditioner for aquarium keepers using reverse osmosis (RO) or deionised (DI) water. It restores and maintains general hardness (GH) by replacing physiologically relevant minerals removed during RO/DI filtration, making it suitable for fish adapted to mineralised water.
Seachem’s proprietary salt blend contains both “soft” salts, including sodium and potassium, and “hard” salts, including calcium and magnesium. Restoring mineral content helps support the salt-and-water balance required by fish kept in water with low mineral levels.
Key Benefits
- Restores and maintains aquarium GH after RO or DI filtration.
- Replenishes calcium, magnesium, sodium and potassium salts.
- Raises GH by 1 meq/L (2.8 dGH) at the stated dosage.
- Designed for restoring mineral content in purified aquarium water.
Dosage
- Add 5 mL (1 capful) per 40 L (10 US gallons) to raise GH by 1 meq/L (2.8 dGH).
- For RO or DI water, the recommended restoration level is 1–2 meq/L: use 5 mL for each 20–40 L (5–10 US gallons).
Suitable For
- Aquariums filled or topped up with RO or DI water.
- Fish whose natural environment has higher mineral levels.
- General hardness restoration in freshwater aquariums.
Specifications
- Ingredients: calcium chloride, magnesium chloride, sodium chloride and potassium chloride.
- Guaranteed analysis per 1 g: calcium 13.00–14.00%; magnesium minimum 1.20%; potassium minimum 0.12%; sodium 0.60–0.70%.
- GH guide: 0–1 meq/L soft; 1–2 moderately soft; 2–3 slightly hard; 3–4 moderately hard; 4–6 hard; 6+ very hard.
What's Included
- 250 ml (0.066 gal) Seachem Replenish.
