MASTERLINE GH PLUS 500g – Remineralizer for RO and Freshwater Aquariums with Calcium, Magnesium and Potassium
MasterLine GH Plus 500g is a professional-grade remineralizer formulated to increase general hardness (GH) in reverse osmosis and freshwater aquariums, without affecting carbonate hardness (KH). It is the ideal solution for preparing stable remineralized water to support the health of fish, shrimp, and aquatic plants.
The balanced formula delivers calcium and magnesium in a precise 4:1 ratio, along with a trace amount of potassium to further support biological functions. The 100% water-soluble salts dissolve quickly and completely, ensuring uniform distribution of essential minerals. Perfect for setups with GH below 6°d, this product helps recreate natural conditions for sensitive species.
Safe for all aquatic life, including shrimp and Caridina species, MasterLine GH Plus promotes plant growth, enhances livestock vitality, and improves the overall stability of freshwater aquariums. The included measuring scoop allows for easy and accurate dosing. After use, keep the container tightly closed to prevent moisture absorption.
