Brightwell Aquatics Alkalin8.3-P

KH Buffer Powder for all Marine Fish and Reef Aquaria. 


  • 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.
  • Formulated by a marine scientist.
  • 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.
