SpaBalancer pH-Minus granules are used for lowering the pH value.
The dosage is strongly dependent on the water hardness, therefore no fixed dosage amounts can be given.
We recommend the following procedure
First measure the pH value of the water.
Add one dosing cup filled to the 50 ml mark with pH-Minus granulate per 1000 liters to the water while the whirlpool pumps are running. Leave the pumps on until everything is well mixed.
After 20 minutes, measure the pH value again. From the measured difference, you can estimate how much pH-Minus you still need to add to the water.
The pH value should be between 6.8 and a maximum of 7.8. The pH value will always rise during the first days / weeks because carbonic acid escapes from the water. Therefore, the pH value must be measured and lowered regularly.
SpaBalancer is our recommendation when it comes to chlorine-free and organic water care.
Never before has it been so easy to keep your hot tub, swim spa or pool clear, clean and odor-free.
