  1. Alkalin 8.3 is a ighly-effective alkalinity(KH)-increasing (“buffer”) solution.

  3. Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
  4. Continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases.
  5. Over 50% stronger than most competing products.
  6. Free of phosphate, silicate, and organic material.
  7. Formulated by a marine scientist.

Dose Rate: 5mL per 110 litres of aquarium water per day until desired alkalinity is reached.
