Heone Fish Water Test Kit GH

GH (General Hardness) testing is important as it measures the amount of calcium and magnesium in your aquarium water — minerals that fish need to stay healthy.

It helps you:

• Keep fish in water that matches their natural habitat
• Prevent stress, illness, and poor growth
• Support proper bone, fin, and egg development
• Improve breeding success
• Maintain stable overall water conditions

In short, correct GH = healthier, less stressed fish and a more stable aquarium environment.
