When to use?
Pond fish require a safe and stable pH to remain healthy. As pond water ages, fish waste and other organic matter uses up the carbonate hardness (KH) that provides this safe and stable pH. If left unchecked, a low KH can lead to unstable water quality, a sudden drop in pH and serious illness in fish.

NT Labs KH – Buffer Up replenishes these essential minerals leading to a safe and stable environment.

How to use?

• Dissolve the powder in a bucket of pond water before adding to the pond.
• Keep out of the reach of children.
• Wash hands well after handling fish and this product.
• Use NT Labs Hardness Test Kit to measure the KH of the pond water. Always keep the KH above 6 °dH for optimal water quality. KH – Buffer Up can also be used to provide additional carbonate hardness where tap water is naturally low in hardness minerals.

FAQs:
Q: Does your KH buffer contain phosphates? A: No, our KH buffer products are both phosphate and nitrate free.
To increase the KH of your pond water by 3-4°dH: Add 50ml powder to: 340 litres (75 imp gallons)
