Brightwell Koralle-VM Vit & Mineral Supplement 17 oz. 500 ml.

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.
