If your HotSpring Highlife Spa is equipped with the FreshWater IQ Dosing mounting plate under the filter cover (see image), you can upgrade your spa with the FreshWater IQ Dosing Start-Up kit for semi-automatic dosing of PH+, PH-, and anti-phosphate.
The FreshWater IQ Dosing system can only be used in combination with the Freshwater IQ Smart Monitoring system.
Optionally, it can be further expanded with the Connected Spa Kit 2
