Aqua Matsya GH Booster is designed for planted aquarium keepers who want greater control over their water. When working with RO/DI water or naturally soft source water, calcium and magnesium often need to be added back in measured, dependable amounts. GH Booster does exactly that — raising general hardness (GH) through a sulfate-based mineral profile while leaving KH unchanged.

Calcium supports plant structure and growth, while magnesium plays a central role in chlorophyll function and overall plant metabolism. By restoring these essential minerals in a focused, planted-tank-safe format, GH Booster helps create a more stable foundation for healthy aquatic plant development.

Its formula is concentrated, easy to pre-mix, and designed to clear quickly under flow. For hobbyists preparing RO water, adjusting soft water, or building a more controlled remineralisation routine, GH Booster offers a precise and premium solution that fits naturally into a serious planted aquarium system.

Key benefits

• Raises GH only, without increasing KH
• Adds calcium (Ca²⁺) and magnesium (Mg²⁺) for healthier planted aquariums
• Especially useful for RO/DI water and very soft water setups
• Sulfate-based mineral profile with no chloride salts intentionally added
• Concentrated formula with high solubility at dose
• Slight haze, if seen, clears within minutes under flow
• Designed for planted tanks and shrimp-safe dosing when used as directed

---

Best suited for

• RO/DI-based planted aquariums
• Soft-water planted tanks that need calcium and magnesium remineralisation
• Shrimp keepers and planted tank hobbyists who want precise GH control
• Water-change preparation routines and RO mixing barrels
• Hobbyists who want to raise GH without affecting KH

Recommended dosage

6 g in 80 L raises GH by 2.5, delivering approximately:

• Calcium (Ca): 11.7 ppm
• Magnesium (Mg): 3.4 ppm

These values are calculated from stoichiometry. Actual results may vary depending on water chemistry and GH test resolution.

How to use

Recommended method

1. Measure the required dose based on your target GH.
2. Pre-mix the powder in approximately 1 L of water in a cup or container.
3. Add slowly into a high-flow area of the tank, or add to your RO mixing barrel.
4. Test GH after mixing and adjust gradually.

Why calcium and magnesium matter

Calcium supports cell structure and healthy growth.
Magnesium is central to chlorophyll function and overall plant metabolism.

This makes GH Booster especially relevant in setups where purified or very soft water leaves planted aquariums short of the mineral backbone needed for stable, healthy plant development.

What makes it different

GH Booster is designed as a GH-only remineraliser. That matters because many hobbyists using RO/DI water want to restore calcium and magnesium without also pushing carbonate hardness upward. Aqua Matsya GH Booster is built specifically for that role, giving planted aquarium keepers cleaner control over their water preparation routine.

Compatibility & notes

• Designed for planted tanks
• Shrimp-safe dosing when used as directed
• Do not overdose dramatically in one shot
• Raise GH gradually for sensitive livestock
• Best used when preparing RO water or during water changes

Storage & handling

Store tightly closed in a cool, dry place and keep away from moisture. Close the cap immediately after use. Retain the inner seal and silica gel desiccant after opening to help protect the product from moisture. For aquarium use only. Not for human or animal consumption.
