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.

FAQ
How should I dose Aquaforest KH Pro in my reef aquarium?
The dosage depends on the current KH level and the desired adjustment. Follow the recommended dosage based on tank volume and current alkalinity. Start with a small amount and monitor pH and KH levels closely.
Can Aquaforest KH Pro be used in a mixed reef aquarium?
Yes, Aquaforest KH Pro is suitable for mixed reef aquariums and helps maintain stable carbonate hardness essential for coral health.
Does KH Pro affect other water parameters besides KH?
KH Pro primarily increases carbonate hardness and adds potassium. It does not significantly alter nitrate, phosphate, or other major water parameters when used as directed.

Piers Taylor –
Used KH Pro in my SPS tank after a sudden pH drop. It stabilized the water within hours. The formula is easy to mix and the KH levels rose steadily. Corals showed no signs of stress after use.
Oliver Walker –
Good product for maintaining KH in a larger reef system. I added it once a week during water changes. The potassium boost seems to support coral growth slightly better than before.
Harry Watson –
After switching from KH Plus Lab, I noticed more consistent pH levels. KH Pro works faster and is more effective in correcting drops. I now use it as a preventive measure during water changes.
Connor Paterson –
Works well in a mixed reef setup. I mixed it with my weekly water change and saw stable KH levels over several weeks. No adverse effects on fish or invertebrates.

The concentrated formula makes it easy to dose accurately. I’ve used it for three months now and my coral skeletons are growing steadily. Highly recommend for reef keepers with fluctuating alkalinity.
