JBL Aquadur is a mineral salt mixture designed to enhance water quality in freshwater aquariums, particularly those using soft or reverse osmosis (RO) water. It reliably increases carbonate and general hardness, helping to maintain consistent water values essential for the health of fish, invertebrates, and aquatic plants.

This formula prevents sudden pH drops by stabilising carbonate hardness (KH) and supports a healthy aquatic environment by preventing mineral deficiencies. Ideal for remineralising RO water or adjusting soft tap water, Aquadur ensures a stable, fish-safe environment. The included measuring spoon allows for precise dosing and ease of use.

Key Features:

• Increases carbonate hardness (KH) and general hardness (GH)
• Stabilises pH levels to prevent sudden acidity drops
• Ideal for remineralising osmosis or soft water
• Prevents mineral deficiency in fish and invertebrates
• Simple dosing with included measuring spoon

JBL Aquadur is a practical solution for maintaining constant, healthy water conditions in freshwater aquariums. Whether preparing water for initial use or adjusting water parameters after partial changes, it helps achieve optimal conditions for aquatic life.

• Estimated yield: Treats up to 3000L of water at 1°dKH and 1.6°dGH
