If Calcium Hardness is <150ppm: Add 500mL of OMNI Spa pH Anchor per 1,000 litres directly into the spa with the pump operating and heater off.

Add directly into the spa with the pump operating and heater off. Add an additional 30mL of OMNI Spa pH Anchor per 1 000 litres once a week to maintain proper pH levels. After dosing your spa with OMNI Spa pH Anchor, you may notice some initial cloudiness. This indicates that the product is working. It is recommended that you run your filter to clear the cloudiness. Monitor your filter pressure during this time and backwash as necessary. The water should clear completely within 24 hours. The heater MUST remain OFF until the spa is clear of any cloudiness.
