Definition: Water Hardness refers to the concentration of dissolved minerals, primarily calcium and magnesium, in aquarium water. It is a crucial parameter in water chemistry that affects fish health, plant growth, and overall aquarium stability.
Key Points:
- Types: Includes General Hardness (GH) and Carbonate Hardness (KH or Alkalinity).
- Measurement: Typically measured in degrees (dGH/dKH) or parts per million (ppm).
- Importance: Different fish species have specific hardness requirements for optimal health and breeding.
- Adjustment: Can be increased using mineral supplements or decreased through water softening methods or dilution with softer water.
