We created highly concentrated KH Pro to easily and efficiently restore the correct carbonate hardness (KH) in marine aquariums, giving you confidence that your aquarium is in excellent condition. KH Pro was developed as a more concentrated, efficient version of the popular KH Plus Lab. KH Pro provides even stronger action, offering immediate improvement in water parameters, which is crucial in emergency situations such as sudden changes in water chemistry.

Thanks to its innovative formula, KH Pro not only effectively raises KH levels but also enriches the water with potassium, essential for the healthy growth and development of corals and other marine organisms. Each 10 ml of the product per 100 liters of water increases potassium levels by 1 mg/l, contributing to maintaining optimal aquarium conditions and supporting natural biological processes.

KH Pro is designed for advanced aquarists who need quick and effective solutions for managing water parameters in their tanks. The product is ideal for use in both large tanks and smaller aquarium ecosystems, where water parameter stability is crucial for the health and well-being of marine organisms. Additionally, due to its high concentration, it allows for storing fewer containers, saving space around the aquarium.

Benefits of using KH Pro: 

• Fast action: Immediate replenishment of carbonate hardness in emergency situations.
• Potassium enrichment: Additional potassium supports healthy coral growth.
• Precise dosing: 5 ml of KH Pro per 100 liters of water increases KH by 0.5 dKH.
• Safety: Recommended dosing minimizes the risk of shock to marine organisms.

Dosage instructions: To avoid shock to marine organisms, do not increase carbonate hardness by more than 0.5 dKH within 24 hours.
