Description

Colombo GH+ for Koi & Garden Ponds – Increase General Hardness

 

Colombo GH+ specifically increases the general hardness (GH) in pond water and provides the pond with essential minerals.

General hardness describes the amount of dissolved minerals in water, particularly calcium and magnesium. These minerals are important for healthy Koi, stable water values, and a functioning biological balance in the pond.

If the GH is too low, a mineral deficiency can occur, which has a negative impact on fish, plants, and filter biology.

With Colombo GH+, the general hardness in the pond is specifically raised and the water is enriched with essential minerals. This creates stable water conditions for Koi, pond fish, and aquatic plants.

 

Who is it suitable for?

🐠 Koi keepers with low general hardness in the pond
💦 Pond owners with mineral deficiencies in the water
⚖️ For stabilizing water values in Koi and garden ponds
