Brightwell Potassion Concentrated Potassium 17 oz. 500 ml.

Highly-effective alkalinity(KH)-increasing (buffer) solution. 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. Continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases. Over 50% stronger than most competing products. Free of phosphate, silicate, and organic material. Formulated by a marine scientist. Liquid Royal Item Number: ABAPTS500
