JBL ProAqua Test KH – Carbonate Hardness Test Kit

The JBL ProAqua Test KH is a precise and easy-to-use water testing solution for determining carbonate hardness (KH) in both freshwater and marine aquariums, as well as garden ponds. Designed for accurate assessment of water’s buffering capacity, this test ensures stable pH levels, which are critical for the health of aquatic life and the success of CO₂ fertilization systems.

Regular testing with the JBL ProAqua Test KH helps prevent dangerous pH fluctuations and supports a balanced aquatic environment by maintaining the correct carbonate hardness level.

Features & Advantages:

• Accurate Measurement: Simple drop test method where 1 drop equals 1 °dKH, allowing precise monitoring of carbonate hardness.

• Versatile Application: Suitable for use in freshwater, saltwater aquariums, and garden ponds.

• Prevents pH Instability: Helps maintain essential buffering capacity to protect fish, plants, and invertebrates from harmful pH swings.

• Supports CO₂ Fertilization: Ensures optimal conditions for CO₂ supplementation in planted aquariums by maintaining carbonate hardness at recommended levels.

• User-Friendly: Quick and straightforward procedure, ideal for regular water parameter monitoring by both hobbyists and professionals.

Recommended Carbonate Hardness Levels:

• Freshwater aquariums: 5–16 °dKH

• CO₂ fertilized aquariums: Minimum 5 °dKH

• Marine aquariums: 7–13 °dKH

• Garden ponds: Minimum 5 °dKH

An essential tool for maintaining water quality and ensuring the long-term success of aquarium and pond ecosystems.
