Quantum Blackwater Extract 1000ml

Blackwater Extract is designed to naturally soften water (by binding high levels of calcium and magnesium), provide natural anti-bacterial properties, promote vibrant colouration and improve overall water quality. Organic Acids, Indian Almond Leaf, Catappa Leaf and Alder Cones have their beneficial components gently extracted without the use of harsh chemicals, leaving behind the plant debris among other impurities to be filtered out, giving a rich, dark extract without the addition of artificial colours or colour enhancers.


– Deionised Water

– Organic Acids

– Indian Almond Leaf Extract

– Catappa Leaf Extract

– Alder Cone Extract


Shake vigorously for 20-30 seconds before each use, this product is not to be used with a dosing pump. For dosing directly into the aquarium – we recommend diluting with your aquarium water first, then slowly adding into high flow. For dosing into water change
