Aquaforest KH Plus New 250ml is a professional marine aquarium carbonate hardness supplement designed to raise and stabilise KH levels in reef aquariums. Carbonate hardness, also known as alkalinity, is one of the most important parameters in marine systems, helping support stable pH, coral calcification, skeletal development and overall reef aquarium balance. Ideal for reef aquariums, nano reefs, SPS coral systems, LPS coral systems and mixed reef tanks, Aquaforest KH Plus New provides a convenient liquid solution for correcting KH deficiency and sudden alkalinity drops. The compact 250ml bottle is ideal for smaller marine aquariums, nano reef systems, occasional KH correction or aquarists who want precise alkalinity control without purchasing a larger bottle. Key Features Professional KH and alkalinity supplement for marine aquariums Raises and helps stabilise carbonate hardness Supports stable pH in reef aquarium systems Helps restore ionic balance after sudden KH drops Provides carbonate ions needed for coral skeleton growth Suitable for SPS, LPS, soft coral and mixed reef aquariums Liquid formula for accurate manual dosing Suitable for use with automatic dosing systems where required Compact 250ml bottle, ideal for nano reefs and smaller marine systems Designed for marine and reef aquarium use Product Overview Aquaforest KH Plus New has been developed for marine aquarists who need to increase carbonate hardness safely and accurately. In reef aquariums, KH is gradually consumed by corals, coralline algae, clams and other calcifying organisms. If carbonate hardness falls too low, pH stability can be affected, coral growth may slow, and the aquarium can become less stable overall. This ready-to-use liquid KH supplement allows aquarists to correct alkalinity levels based on reliable water testing and the actual consumption of the aquarium. It is particularly useful in aquariums where KH demand is higher than can be maintained through water changes alone. Benefits for Reef Aquariums Aquaforest KH Plus New helps support stable reef water chemistry by replenishing carbonate hardness when levels are depleted. KH is closely linked to pH stability and coral calcification, making it especially important in aquariums containing SPS corals, LPS corals, clams and coralline algae. Maintaining the correct KH level also supports the relationship between alkalinity, calcium and magnesium. These three parameters work together in reef aquariums, and stable levels are essential for coral health, skeletal growth and long-term reef success. Suitable For Aquaforest KH Plus New 250ml is suitable for: Marine aquariums Nano reef aquariums Reef aquariums SPS coral systems LPS coral systems Mixed reef aquariums Soft coral aquariums Aquariums with clams or coralline algae growth Marine systems with occasional KH correction needs Manual dosing and controlled supplementation routines This product is designed for marine aquarium use only and should be dosed according to KH test results. How to Use Test the carbonate hardness level in the aquarium before dosing. Dose Aquaforest KH Plus New according to the measured KH level and the desired target level. Add the supplement to an area of good water movement, or dose slowly using an automatic dosing pump for improved stability. For best results, raise KH gradually and avoid sudden parameter changes. Regular testing is recommended to calculate the aquarium’s daily or weekly carbonate hardness consumption. Dosing Advice Aquaforest states that 10ml of KH Plus raises carbonate hardness by approximately 0.25 dKH in 100 litres of aquarium water. Aquaforest recommends maintaining carbonate hardness at around 6.5–8.5 dKH in reef aquariums. Do not raise KH by more than 0.5 dKH per 24 hours. Always base dosing on accurate water test results. Magnesium should be within the recommended range before making major calcium and alkalinity adjustments. In reef aquariums, KH, calcium and magnesium work closely together, so all three parameters should be monitored regularly. When to Use Aquaforest KH Plus New is useful when: KH levels are too low in a marine aquarium A reef aquarium has measurable alkalinity consumption pH stability is affected by low carbonate hardness SPS or LPS corals require stable mineral levels Coralline algae or clams are consuming carbonate hardness A smaller reef aquarium needs occasional KH correction A dosing routine needs separate KH control Water testing shows a gradual decline in alkalinity Storage Store in a cool, dry place away from direct sunlight. Keep the bottle tightly closed when not in use. Keep out of reach of children. This product is intended for aquarium use only and is not suitable for consumption.

Aquaforest KH Plus New is a practical choice for reef keepers who need accurate carbonate hardness supplementation in a ready-to-use liquid format. Stable KH is essential for pH stability, coral calcification, skeletal development and long-term reef aquarium health, particularly in aquariums with growing hard corals and coralline algae. The 250ml size is ideal for nano reefs, smaller marine aquariums and aquarists who only need occasional KH correction. Whether used manually or as part of a controlled dosing routine, Aquaforest KH Plus New helps maintain stable alkalinity levels and support long-term coral health. Recommended For Aquaforest KH Plus New 250ml is recommended for marine aquarists maintaining reef aquariums where carbonate hardness needs to be increased or stabilised. It is especially useful for nano reefs, SPS, LPS and mixed reef systems where stable KH, calcium and magnesium are important for coral growth, calcification and overall reef balance.
