Aquaforest KH Plus Lab 2L – Concentrated Alkalinity & Carbonate Hardness Supplement for Reef Aquariums

Maintain stable carbonate hardness and support healthy coral growth with Aquaforest KH Plus Lab 2L, a highly concentrated alkalinity supplement specially formulated for marine and reef aquariums. Designed to correct low carbonate hardness (KH) and replenish alkalinity consumed by corals, this liquid solution helps maintain the balanced water chemistry essential for successful reefkeeping.

Carbonate hardness is one of the most important parameters in a reef aquarium. It reflects the water's acid-neutralizing capacity and helps maintain stable pH conditions. Adequate alkalinity also provides the bicarbonate and carbonate needed by SPS and LPS corals to build their calcium carbonate skeletons.

As stony corals grow, they continuously consume alkalinity through calcification. Without appropriate supplementation, KH levels can gradually decline, potentially affecting coral skeletal development and aquarium stability.

Aquaforest KH Plus Lab provides a concentrated solution for correcting measured alkalinity deficiencies and maintaining suitable carbonate hardness in established reef systems.

Supports Healthy Coral Growth & Skeletal Development

SPS and LPS corals require a consistent supply of calcium and alkalinity to form and maintain their skeletons.

Aquaforest KH Plus Lab helps replenish alkalinity consumed during coral calcification, supporting the mineral environment required for normal skeletal development.

Maintaining appropriate carbonate hardness is particularly important in established reef aquariums containing rapidly growing stony corals.

Helps Maintain Stable Aquarium pH

Carbonate hardness contributes to seawater's natural buffering capacity.

By maintaining adequate alkalinity, reefkeepers can help reduce the risk of sudden pH fluctuations caused by changes in dissolved carbon dioxide and biological activity.

While alkalinity supplementation does not replace proper aeration or carbon dioxide management, maintaining stable KH is an important part of balanced reef aquarium chemistry.

Highly Concentrated Formula for Precise KH Adjustment

Aquaforest KH Plus Lab 2L features a concentrated liquid formula designed for efficient carbonate hardness replenishment.

Just 10ml increases carbonate hardness by approximately 0.5 dKH in 100 liters (27 US gallons) of aquarium water.

The recommended carbonate hardness range is 6.5–8.5 dKH.

To protect sensitive aquarium inhabitants from rapid changes in water chemistry, do not increase carbonate hardness by more than 0.5 dKH within 24 hours.

The concentrated formulation is particularly useful for reefkeepers who need accurate alkalinity adjustments based on measured aquarium requirements.

Supports Balanced Reef Aquarium Chemistry

Alkalinity, calcium, and magnesium are closely connected in marine aquarium water chemistry.

Maintaining appropriate magnesium concentrations helps reduce unwanted calcium carbonate precipitation, making it easier to manage calcium and alkalinity levels.

Before correcting significant alkalinity deficiencies, reefkeepers should check magnesium and calcium levels to ensure the aquarium's mineral balance is appropriate.

Aquaforest KH Plus Lab can be incorporated into a carefully monitored supplementation program based on regular KH testing and actual aquarium consumption.

Supplied in a generous 2-liter (2000ml) bottle, this supplement is suitable for reefkeepers maintaining established coral systems or aquariums with ongoing alkalinity demand.

Available at Reef freaks, Aquaforest KH Plus Lab 2L provides a practical solution for controlled alkalinity management and stable reef aquarium conditions.
