Aquaforest KH PRO 2000ml
Aquaforest KH Pro 2000ml is a highly concentrated marine aquarium supplement designed to quickly restore and maintain carbonate hardness in reef aquariums. Developed as a stronger and more efficient version of KH Plus Lab, KH Pro helps correct sudden alkalinity drops, support stable pH and maintain the carbonate levels required for healthy coral growth and skeletal development.
Ideal for experienced reef keepers, SPS systems, mixed reef aquariums and larger marine systems, Aquaforest KH Pro provides fast, precise KH adjustment in a concentrated liquid formula. In addition to raising carbonate hardness, it also enriches the water with potassium, supporting coral health, growth and natural biological processes in the aquarium.

- Designed for advanced reef aquarists and precise parameter control
Product Overview
Aquaforest KH Pro has been developed for marine aquarists who need a fast and efficient way to raise carbonate hardness in reef aquariums. Carbonate hardness, also known as KH or alkalinity, is one of the most important parameters in a marine aquarium because it helps stabilise pH and provides carbonate ions used by corals and other calcifying organisms.
In reef aquariums, KH is continuously consumed by corals, coralline algae and other organisms as they build calcium carbonate skeletons. If KH drops too low or changes too quickly, corals may become stressed and aquarium stability can suffer. KH Pro provides a concentrated solution for restoring carbonate hardness safely and accurately.
Benefits for Reef Aquariums
Aquaforest KH Pro helps maintain one of the key foundations of reef aquarium stability: consistent alkalinity. Stable KH supports coral calcification, healthy skeletal growth, pH balance and the long-term health of SPS, LPS and other calcifying reef organisms.
Because KH Pro is highly concentrated, smaller doses can make effective adjustments compared with weaker KH products. This makes it especially useful for larger aquariums, high-demand coral systems and aquarists who need efficient correction of carbonate hardness without storing large numbers of bottles.
Suitable For
Aquaforest KH Pro 2000ml is suitable for:
- Marine aquariums
- Reef aquariums
- SPS coral systems
- LPS coral systems
- Mixed reef aquariums
- Larger reef systems
- High-demand coral aquariums
- Aquariums with falling KH levels
- Advanced reef dosing routines
- Manual dosing or automatic dosing pumps
This product is designed for marine aquarium use and should be dosed according to regular water testing and actual aquarium consumption.
How It Works
Aquaforest KH Pro raises carbonate hardness by adding carbonate alkalinity to the aquarium water. This helps restore the carbonate ions needed for coral skeleton formation and helps support stable pH.
KH Pro also enriches the aquarium with potassium. Potassium is an important element in reef aquariums and supports healthy coral growth, colour and natural biological processes when maintained within suitable levels.
How to Use
Shake well before use.
Dose Aquaforest KH Pro slowly into a high-flow area of the aquarium or sump. Test KH before dosing, calculate the required adjustment carefully and dose gradually.
Official dosing guidance states that 5ml of KH Pro per 100 litres of aquarium water increases carbonate hardness by 0.5 dKH.
Do not increase carbonate hardness by more than 0.5 dKH within 24 hours.
Dosing Advice
Always test KH before and after dosing. Avoid dosing based only on guesswork, as alkalinity changes can strongly affect coral health.
For daily maintenance, calculate the aquarium’s average KH consumption by testing at the same time each day over several days. Once the daily drop is known, KH Pro can be dosed manually or through a dosing pump to maintain stability.
If using KH Pro with a dosing pump, split the daily dose into several smaller additions to reduce parameter swings.
When to Use
Aquaforest KH Pro 2000ml is useful when:
- Carbonate hardness is lower than desired
- KH has dropped suddenly
- A reef aquarium consumes alkalinity quickly
- SPS or LPS corals require stable alkalinity
- pH stability needs support
- A larger aquarium needs concentrated KH dosing
- A high-demand coral system requires precise parameter control
- KH levels fall between water changes
- An advanced reef dosing routine is being used
- Space-saving concentrated supplementation is preferred
Reef Stability Advice
Stable KH is usually more important than chasing a specific number. Many reef aquariums are maintained successfully within a KH range of around 6.5–8.5 dKH, depending on nutrient levels, coral type and reef-keeping method.
Avoid raising alkalinity too quickly, especially in low-nutrient reef aquariums, as sudden KH increases can stress corals. Always keep calcium, magnesium, salinity, nitrate and phosphate in suitable balance alongside alkalinity.
Before making major KH adjustments, check magnesium levels, as magnesium helps support the balance between calcium and carbonate hardness in seawater.
Potassium Enrichment
Aquaforest KH Pro also adds potassium to the aquarium. Official guidance states that 10ml of KH Pro per 100 litres increases potassium by 1mg/l.
Potassium is important for coral health and biological function, but it should still be monitored in systems receiving regular concentrated supplementation. In high-demand reef aquariums, periodic potassium testing can help confirm that levels remain appropriate.
Compatibility Advice
Do not mix Aquaforest KH Pro directly with other concentrated supplements.
Dose separately from calcium, magnesium and trace element products to avoid precipitation or unwanted reactions. When using multiple supplements, allow each product to disperse fully before adding another.
KH Pro is a strong concentrated supplement and is best suited to aquarists who test regularly and understand reef parameter management.
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 marine aquarium use only and should not be consumed.
