I have a Viking 1 spa and am wanting to install an Ozonator hoping to cut down on chemical usage etc. My question is anyone know what type or maybe part # that i need to look for and also opinions on if it is a good idea .

You need to look for a hose with no connector - plugged somewhere underneath the spa in the area of the equipment compartment. If you find something then post back your results.

Yes it has a connection at the bottom of tub below where the light is in the front from what i have read that is for ozonator.
