Brightwell Aquatics Alkalin8.3 2 Liter KH Buffer (2000 ml) Marine and Reef Alkalinity Buffer
Concentrated KH Buffer Supplement for All Marine Fish and Reef Aquaria
- 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
- 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 phosphates, silicate, and organic material.
- Formulated by a marine scientist.
Alkalinity, also referred to as carbonate hardness or buffering capacity, is essentially a means of quantifying the stability of pH in a solution, such as aquarium water. Alkalinity is of extreme importance in a marine aquarium, owing to the manner in which it influences pH. In an aquarium, weak acids formed by oxygen respiration and the decomposition of organic material gradually deplete alkalinity. If left unchecked, the alkalinity drops below a critical level and pH begins to fluctuate more wildly than is normally suggested (a daily pH shift of +/-0.2 is normal in marine aquaria), causing stress to livestock. Alkalinity is also depleted by reef-building organisms during the production of aragonite (~60% carbonates by weight), and is therefore very important for their rapid growth.
Maintaining the alkalinity in marine aquaria between 7 - 12 dKH (2.5 - 4.3 meq/L) will generally maintain pH within the desired range. The rate at which alkalinity is depleted in a reef aquarium is determined by the stocking density of reef-building livestock, type of lighting, rate of water circulation, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of alkalinity supplementation. Once the rate of alkalinity depletion in the aquarium has been determined, the proper dosing rate of this product can be easily calculated. It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements be used to establish natural seawater parameters in the reef aquarium, providing a stable ionic foundation on which to build.

All Brightwell Aquatics liquid water care supplements are made with purified water and high purity materials. We develop formulae for aquaria based on empirical data, using observation and measurement rather than theory.
Instructions and Guidelines
Basic: Shake product well before using. 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, 250 ml treats up to 1,500 US-gallons (5,678 L).
Note: If pH does not reach desired level when using this product as directed, such as when gas exchange in the aquarium is insufficient, addition of a pH-increasing product (i.e. Brightwell Aquatics pH+) may be required. Follow manufacturer’s directions for using such a product regardless of which one is used.
Caution: Contains carbonate and bicarbonate salts; harmful if swallowed. If swallowed: give water, get medical attention. May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children. Not for human consumption.
