KH Buffer Powder for all Marine Fish and Reef Aquaria.
Overview
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.
