Seachem Replenish
Seachem Replenish is a liquid mineral supplement designed to restore general hardness (GH) and essential minerals to freshwater aquariums, particularly when using RO or DI water. It replaces minerals removed during purification, helping create appropriately mineralised water for freshwater fish.
Replenish contains a balanced blend of calcium, magnesium, potassium and sodium salts to increase GH in a controlled and easy-to-dose liquid format. It is particularly useful for aquariums where purified or naturally very soft water needs remineralising before use.
Key Features
- Restores and maintains general hardness (GH) in freshwater aquariums
- Replenishes important minerals removed by RO and DI filtration
- Contains calcium, magnesium, potassium and sodium salts
- Convenient liquid formula for straightforward dosing
- Helps prevent osmotic stress associated with inadequately mineralised water
- Ideal for preparing RO/DI water for freshwater fish
- 500 mL bottle
Directions
Add 5 mL per 40 L of water to increase GH by approximately 1 meq/L (2.8 dGH).
When remineralising RO or DI water, a restoration level of 1–2 meq/L is recommended, equivalent to approximately 5 mL per 20–40 L. Always consider the requirements of the fish you are keeping when setting your target GH.
Suitable For
- Freshwater aquariums
- Remineralising RO or DI water
- Aquariums using very soft source water
- Increasing and maintaining general hardness (GH)
- Freshwater fish requiring mineralised water
Simply Fish Tip
For planted aquariums, Seachem Equilibrium is generally the better choice for restoring GH. Replenish contains sodium and chloride, so it is primarily suited to freshwater fish aquariums without live plants.
