Alka – Down 1,5kg

Alka Down reduces the alkalinity of your hot tub and helps keep your spa water in balance.

If the alkalinity is greater than 120 mg/l, you may experience problems with blocked pH and cloudy water.

You should measure and possibly adjust the alkalinity at each water change or if you experience problems maintaining a stable pH between 7.0-7.4.

The alkalinity should be between 80-120 mg/l.
