500 mL
Continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases.
Helps increase pH Stability in an aquarium by raising the alkalinity.
Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
Over 50% stronger than most competing products.
Free of phosphates, silicate, and organic material.
Instructions
Add product at the maximum rate of 5 ml (1 capful) per 30 US-gallons daily until the desired alkalinity is attained, then dose daily or weekly as needed (see below) to maintain alkalinity between 7 – 12 dKH. When used in this fashion, 500 ml treats up to 3,000 US-gallons (11,200 L)


1 ml of Alkalin8.3 will increase the alkalinity in 3.785 L (1 gallon) of water by 3.1 dKH.
