I recently bought a new hot tub that is 4 years old. It is in great shape but I see that people say to replace the ozonator every 5 years or so. I dont want to replace it if it is working properly. How do I know if its working? It is a cal spa ozonator. Before you flame me for buying a Cal Spa, it was used and in great shape without warranty anyway so their crappy customer service and warranty didnt come into play for me.
Thanks Guys
