Carbonate Hardness Increaser – (kH) Generator

Targeted Alkalinity & pH Stability for Aquaculture Systems

Targeted support for maintaining stable pH levels

Pure Aquatics Carbonate Hardness Increaser – (kH) Generator is a high-quality powdered buffering agent formulated to support stable, resilient pH conditions in aquatic life support systems. It provides a balanced spectrum of carbonates and bicarbonates to adjust and maintain alkalinity (kH), helping prevent pH crashes and fluctuations that can stress livestock and impair system performance.

By optimising carbonate hardness, kH Generator plays a critical role in maintaining water chemistry stability and supporting efficient biological filtration.

Key Benefits

• Maintains Stable pH – Adjusts carbonate hardness (kH) to buffer against rapid pH changes
• Optimises Water Chemistry – Creates a more resilient aquatic environment for livestock
• Supports Biofilter Performance – Essential for biofilter conditioning, nitrification efficiency, and long-term biological stability
• Fast Acting & Easy to Use – Powdered format allows precise dosing and rapid system integration
• Professional Grade – Suitable for commercial aquaculture, RAS, aquaponics, and advanced aquatic systems

How It Works

Carbonate Hardness Increaser – (kH) Generator provides the buffering capacity that protects aquatic systems from acidification caused by biological processes such as nitrification. Over time, alkalinity is consumed, leading to declining pH and reduced biofilter efficiency.

Pure Aquatics Carbonate Hardness Increaser – (kH) Generator replenishes essential carbonates and bicarbonates, restoring alkalinity levels and ensuring consistent pH conditions that promote livestock health and optimal biofilter performance.

Typical Applications

• All aquatic life support systems
• Recirculating Aquaculture Systems (RAS)
• Aquaculture tanks and ponds
• Aquaponic systems
• Systems requiring controlled pH and alkalinity management

Function:

• Raises and balances pH
• Maintains healthy, stable carbonate hardness (kH)

Indicative Dosage & Use Instructions

Dose Rate: 4 g per 100 L of system water increases alkalinity by approximately 20 ppm

Monitoring: Always monitor both pH and kH during adjustments

Mixing Instructions:

• • Slowly add the powder to a bucket or container of water (best practice: add powder to water, not water to powder)
  • Mix thoroughly until dissolved
  • Introduce the solution into an area of high water flow for even distribution

Avoid rapid changes to alkalinity. Gradual adjustments are recommended to maintain system stability and livestock health.

Best used with:

NMI+, Bloom, Ammonium Chloride and Sodium Nitrite
