REMIN GH&KH is a specially balanced blend of minerals for remineralizing RO (reverse osmosis) or DI (deionized) water used in aquariums with aquatic plants.
The ingredients meet the needs of both aquatic plants and animals. Additional natural compounds help minimize plant stress during water changes.
The product is safe for fish and invertebrates, and contains no sodium or potassium. Use in aquariums with injected CO₂.

• Easily dissolves in water for convenient and quick dosing.
• Optimally replenishes minerals essential for plant growth.
• Natural compounds reduce stress and support faster recovery after replanting, trimming, or water changes.
• Optimized Ca:Mg ratio ensures healthy plant growth.
• Potassium-free – allows for separate control over potassium levels.
• Sodium-free – excess sodium can inhibit plant development.
• Contains carbonate – essential for most aquatic plants and animals.

20 ml ( ~20 g) spoon (included) per 146 L (~1.4 g → 10 L) :
28.5 ppm Ca, 8.7 ppm Mg, 34.2 ppm SO₄, 6 °GH, 4 °KH.

20.8 % Ca, 6.3 % Mg, 31.2 % CO₃, 25.0 % SO₄.

When choosing between REMIN GH and REMIN GH&KH, consider the needs of your aquarium plants and animals. If you are growing plants that prefer very soft water – such as Tonina sp., Eriocaulon sp., Syngonanthus sp. – we recommend using REMIN GH. If your aquarium plants are less sensitive to water softness, REMIN GH&KH is the better option, as it also increases carbonate hardness (KH) and helps stabilize pH. Important: Using REMIN GH alone (without KH) with injected CO₂ may cause a sharp drop in pH due to the absence of a carbonate buffer. Use our calculator to determine the ideal GH and KH values for your aquarium

Keep out of reach of children. Avoid contact with eyes. Do not ingest. Store in a cool, dry, and dark place.
Temporary cloudiness or discoloration of aquarium water may occur after use – this does not affect product performance.
