NT Labs KH – Buffer Up

If your pH swings morning to night, low carbonate hardness (KH) is often the cause. NT Labs KH – Buffer Up is formulated to raise and stabilise KH levels, helping to prevent sudden pH drops in pond water.

KH acts as a buffer – it resists rapid changes in pH, keeping conditions steadier for koi and ornamental fish.

Why KH Matters

• Helps stabilise pond pH
• Reduces risk of sudden pH crashes
• Supports biological filter performance
• Useful after heavy rain or large water changes

When KH drops too low, ponds can become unstable quickly. Keeping it topped up gives your system a safety net.

When To Use KH – Buffer Up

• If water tests show low KH
• After prolonged rainfall
• Following significant water changes
• When maintaining stability in soft water areas

Always test first so you know how much adjustment is needed.

How To Apply

• Test current KH with a reliable test kit.
• Calculate the correct dose based on pond volume.
• Distribute evenly around the pond with pumps running for circulation.

Avoid large, sudden increases – gradual adjustments are safer for fish.

Safety Notes

• Use strictly as directed on the product label.
• Do not overdose.
• Store in a cool, dry place away from children and pets.

Stable water means less stress for your koi and more consistent filtration performance.

Clear water, happy koi, less hassle.
