Brightwell Alkalin 8.3 P Kh Buffer 250g

Brightwell Alkalin 8.3 P Kh Buffer 250g

SKU: 810086010981

KH Buffer Powder for all Marine Fish and Reef Aquaria.


  • Unlike single component KH products such as sodium carbonate, Alkalin 8.3P is a multi-component automatic buffer that regulates pH and its use makes for a much more stable aquarium.  Eliminates pH and KH instability caused by poor salt mixes and ineffective buffering products.
  • Highly-effective alkalinity-increasing (”buffer”) powdered blend.
  • Helps increase pH stability in an aquarium by raising the alkalinity; continued addition raises
    pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity
    alone increases.
  • Provides a source of carbonates, which make up the majority by weight of aragonite, the
    mineral secreted by reef-building organisms as skeletal material.
  • Determine alkalinity in aquarium with an accurate test kit prior to supplementing. 
  • Do not add this product directly to an aquarium without first diluting in water as directed.
