ABA GH is a salt-based supplement that increases the total hardness of aquarium water. Total hardness is a factor that affects the exchange of fluids between plant and animal tissues and the environment. ABA GH allows you to adjust this parameter to recreate optimal conditions for aquarium species. It is recommended for use when first using ABA Authentic Soil.

Dosage: One 5ml capful in 100 liters raises GH by 4°dGH.
