Colombo GH Test Kit - Water Hardness Test

Colombo GH Test Kit — Accurate Pond Water Hardness Measurement

Ensure your pond water is perfectly balanced with the Colombo GH Test Kit — a professional drop-test kit designed for precise measurement of GH (General Hardness) in ponds and aquariums.

Key Features & Benefits:

• Professional-grade accuracy — reliable measurement of GH (total hardness) for stable pond conditions.

• Clear & simple results — a visible color change makes it easy to determine hardness values with confidence.

• Essential for healthy ponds — GH affects the mineral balance in water, influencing fish vitality, plant growth, and the nitrogen cycle.

• Easy to use — includes step-by-step visual instructions and special test tubes for stress-free testing.

• Complete kit — supplies included for up to 40 GH tests.

• Fast readings — test in minutes and make quick adjustments to maintain optimal water quality.

Why Test for GH (General Hardness)?
GH measures the concentration of dissolved minerals, mainly calcium and magnesium, in pond water. These minerals are vital for:

• Fish health — supporting bone structure, metabolism, and osmoregulation.

• Plant growth — ensuring aquatic plants thrive with proper nutrient uptake.

• Stable water chemistry — helping buffer against sudden pH swings and stress in the pond ecosystem.

Low or unstable GH can lead to weak fish, poor plant health, and water quality problems — making this Colombo GH test kit an essential tool for any pond keeper.

How to Use:

1. Collect pond water in the provided test tube.

2. Add reagent drops as instructed.

3. Watch for the clear color change that indicates GH levels.

4. Compare and record results for ongoing pond management.
