Take control of your pond's water chemistry with the Aquacadabra Catch Up With Your KH™ Bundle. Designed for pond keepers who want stable, healthy water conditions, this carefully selected bundle combines accurate testing with targeted KH adjustment to help prevent pH instability and support fish wellbeing. Low carbonate hardness (KH) is one of the most common causes of pH fluctuations in ponds. These sudden changes can stress fish, impact biological filtration and lead to poor water quality. This bundle provides everything needed to monitor, understand and correct KH levels, helping you maintain a safer and more stable environment for koi, goldfish and other pond inhabitants. Featuring the NT Labs Hardness Test Kit, NT Labs pH Test Kit and NT Labs KH Buffer Up, this complete solution allows you to test, monitor and adjust your pond water with confidence. Key Features Complete pond KH and pH management bundle. Includes NT Labs Hardness Test Kit (GH & KH). Includes NT Labs Aquarium Lab pH 6-9 Test Kit. Includes NT Labs Koi Care KH Buffer Up 1.5kg. Measures both General Hardness (GH) and Carbonate Hardness (KH). Accurately monitors pH levels between 6.0 and 9.0. Helps identify causes of unstable water conditions. KH Buffer Up safely increases carbonate hardness. Supports stable pH levels and healthier pond water. Helps reduce stress caused by fluctuating water chemistry. Suitable for koi ponds, goldfish ponds and ornamental ponds. Easy-to-use liquid drop test kits with clear colour charts. Ideal for routine pond maintenance and water quality management. Suitable for both beginner and experienced pond keepers. Why This Bundle Is So Good Many pond owners focus on pH without understanding that KH is often the factor controlling pH stability. When KH levels become depleted through natural biological processes, pond water can become unstable, increasing the risk of sudden pH crashes that may harm fish and beneficial bacteria. The Catch Up With Your KH™ Bundle removes the guesswork by providing everything required to monitor both hardness and pH levels while also giving you the means to safely correct low KH when needed. Instead of simply treating symptoms, this bundle helps pond keepers understand the root cause of water instability and take corrective action before problems develop. The result is healthier fish, improved biological filtration performance and greater confidence in your pond's water quality. How To Use Step 1: Test Your Water Use the NT Labs Hardness Test Kit to measure both GH and KH levels. Follow the included instructions and compare the results against the supplied colour chart. Step 2: Check pH Stability Use the NT Labs pH Test Kit to determine your pond's current pH level. Regular testing helps identify fluctuations that may indicate low KH reserves. Step 3: Adjust KH Levels If KH levels are below the recommended range, use NT Labs KH Buffer Up to replenish essential carbonate minerals. Dissolve the required amount in a bucket of pond water before adding it evenly around the pond. Step 4: Monitor Regularly Continue testing KH and pH routinely to maintain stable water conditions. For optimal pond health, NT Labs recommends maintaining KH above 6 dKH. Whether you are managing a koi pond or a garden pond, the Catch Up With Your KH™ Bundle provides the tools needed to achieve stable water chemistry, healthier fish and improved pond performance all year round.
