AquaForte PH- 1L / ± 1.500gr

Lowers the PH value (acidity level) of pond water. PH- dosage: 25 ml of PH- is suitable for reducing the value of 500 liters of water by 1 PH (1 liter per 20,000 liters of pond water). Depending on the desired value, dissolve the required amount of PH- in water in a watering can and spread it on the surface of the water. During this operation, take care to touch the plants as little as possible. It is forbidden to reduce the value of the pool water by more than 1 PH per day.

Therefore, before and after each dosing, check the pH value of the pond water. Point of attention: Since when the PH value decreases, the KH value (carbonate hardness) will also decrease, the KH value should be carefully controlled. When the KH value of pond water is less than 2 KH, it is forbidden to use PH-. In this case, the KH value must first be increased with KH+.
