Aquaforest KH Plus 200ml – Carbonate Hardness & Alkalinity Supplement for Reef Aquariums

Maintain stable alkalinity and support healthy coral growth with Aquaforest KH Plus 200ml, a concentrated liquid solution designed to increase carbonate hardness (KH) in marine and reef aquariums.

Formulated to correct low alkalinity levels and help manage sudden drops in carbonate hardness, Aquaforest KH Plus provides an effective way to maintain the balanced water chemistry required for a healthy reef environment.

Carbonate hardness is one of the most important water parameters in marine reef aquariums. It reflects the water's ability to neutralize acids and plays a vital role in maintaining stable pH conditions. Adequate alkalinity also provides the carbonate and bicarbonate availability needed by stony corals to build their calcium carbonate skeletons.

As SPS and LPS corals grow, they consume alkalinity through the calcification process. Without appropriate supplementation, carbonate hardness can gradually decline, potentially affecting coral skeletal development and aquarium pH stability.

Aquaforest KH Plus provides a convenient solution for replenishing alkalinity and maintaining suitable carbonate hardness levels in established reef aquariums.

Supports Healthy Coral Growth & Skeletal Development

Corals require a balanced supply of calcium and carbonate ions to build and maintain their skeletons.

In reef aquariums containing SPS and LPS corals, alkalinity is continuously consumed as corals develop their calcium carbonate structures.

Maintaining appropriate carbonate hardness helps support normal coral calcification and the mineral balance required for skeletal growth.

Aquaforest KH Plus allows reefkeepers to correct measured alkalinity deficiencies and maintain the conditions required for healthy coral development.

Helps Maintain Stable Aquarium pH

Carbonate hardness plays an important role in the natural buffering system of seawater.

Adequate alkalinity helps the aquarium resist rapid pH changes caused by biological activity and fluctuations in dissolved carbon dioxide.

While KH supplementation is not a substitute for proper aquarium aeration or carbon dioxide management, maintaining suitable alkalinity contributes to a stable marine environment.

Aquaforest KH Plus helps replenish depleted carbonate hardness and supports consistent reef aquarium water chemistry.

Precise Carbonate Hardness Adjustment

Aquaforest KH Plus features an easy-to-measure liquid formula designed for controlled alkalinity adjustments.

Just 10ml increases carbonate hardness by approximately 0.25 dKH in 100 liters (27 US gallons) of aquarium water.

The recommended carbonate hardness range for reef aquariums is 6.5–8.5 dKH.

To avoid rapid changes in aquarium chemistry, do not increase alkalinity by more than 0.5 dKH within 24 hours.

For best results, test carbonate hardness regularly and adjust supplementation according to the aquarium's actual alkalinity consumption.

Ideal for SPS, LPS & Mixed Reef Aquariums

Aquaforest KH Plus is suitable for marine aquariums containing stony corals, soft corals, and other reef organisms.

It is particularly useful for established reef systems where coral growth and calcification increase alkalinity demand.

Because calcium, magnesium, and alkalinity are closely related, reefkeepers should monitor these parameters together.

Before making significant calcium or alkalinity adjustments, ensure magnesium levels are within the appropriate range.

Supplied in a convenient 200ml bottle, Aquaforest KH Plus is a practical option for correcting carbonate hardness deficiencies and maintaining stable reef aquarium conditions.

Available at Reef freaks, Aquaforest KH Plus 200ml helps reefkeepers manage alkalinity and support balanced marine aquarium chemistry.
