💧 Why test KH levels in ponds?

The KH level determines how well your pond resists sudden changes in pH. Without sufficient carbonate hardness, water can quickly swing from safe to harmful, stressing your fish and plants. Regular testing ensures:

• Stable pH levels and reduced stress for koi and pond fish

• Better performance of pond treatments and filters

• Long-term pond health and balanced water quality

The Colombo KH Test Kit is trusted by pond keepers for its precision, simplicity, and professional results.
