All About the Product
Product description
GH-Plus
PARTICULARLY ECONOMICAL
- Rapid increase of general hardness (GH)
- Calcium for the pond
- Immediately available for flora and fauna
The general hardness (GH) of pond water should not be less than 1 mmol (5 °dH).
GH-Plus increases general hardness quickly and precisely by replenishing the calcium biologically consumed from the water. Flora and fauna receive this vital macronutrient in an immediately available form. GH-Plus thus ensures a healthy pond climate.
Carbonate hardness is not increased with GH-Plus. For this purpose, the use of TeichFit is recommended.
Our application and dosage recommendation
Use if the general hardness is below 1 mmol (5 °dH). Mix the required dose with approximately 10 liters of water and pour evenly into the pond.
50 ml of GH-Plus per 1,000 liters of pond water increases the general hardness by 0.2 mmol (1 °dH).
