Colombo KH Plus is a fast-acting treatment that increases carbonate hardness (KH) in pond water, helping to stabilise pH levels. Maintaining the correct KH is essential for a healthy pond, as low levels can lead to sudden pH fluctuations that may harm fish and plants.

Key Features:

• Increases carbonate hardness (KH) levels
• Helps stabilise and maintain consistent pH
• Supports a healthier environment for fish and plants
• 100% natural pond treatment
• Fast-acting and easy to apply
• Available in multiple sizes to suit different pond volumes

By restoring KH to the recommended range of 6–8°DH, Colombo KH Plus helps prevent unstable water conditions. Regular monitoring and adjustment can reduce stress on aquatic life and improve overall pond balance.

Dosage:

• 15 ml per 200 litres raises KH by 2°DH
• Dilute in lukewarm water before adding to the pond
• Do not pour directly onto plants
• Test water monthly and adjust as needed

Available Sizes:

• 1L – treats up to 7,000 litres
• 2.5L – treats up to 17,500 litres
• 5L – treats up to 35,000 litres

For ongoing stability once the desired KH level is reached, consider maintaining water balance with Colombo Balantex.
