For the effective decrease oft he pH-value

pH-Minus decreases quickly high (basic) pH-values.
Starting from a pH-value of 9 ammonia is formed in ponds.
pH-Minus helps immediately during acute ammonia poisoning.
By pH-Minus the pH value is not stabilized - therefore we recommend the usage of MineralPro after the pH-value has been decreased.

Application:
Intersperse the weighed out dose evenly on the pond surface.
A short-time turbidity in the water is possible.
Do not intersperse directly on plants.
The filter and UV-devices can remain in operation.
Larger GH-value increases should take place over several days !

Caution:
Fast pH-value changes lead to a health risk for fishes and other water organisms !
The pond water values should not sink more than 1 pH per day.
Please check the pH-value of the water regularly and decrease the pH-value only very slowly.

Dosing:
10 g (0,35 oz) increase the pH-value by 0,1 per 1000 liters (265 gal) pond water.
