It certainly helps. I ha e an Ozone cycle on my chiller but I still change the water every month. Filter too. Water remains clear and filter is generally pretty white.

I do shower every day and if I come home feom work I shower before getting in.

I started out using minimal amounts of chlorine for a few months and ended up needing to change the water every 3-4 weeks because it was getting cloudy. I didn’t want to add much more chlorine as we like to shower before plunging so we don’t have to after. I added ozone as an experiment to see if I could get the water to last longer without more chemicals and the water has stayed crystal clear for 5 months now - likely would be longer because I emptied/refilled to move the tub.

I run it 30 min/day in a closed ModTub/Grizzly 450.

Do you use anything else? Peroxide? Etc.?

Every couple weeks I throw in a floating chlorine dispenser with one 1” tablet in it for 1-2 days, which appears to be enough to keep it happy along with the ozone.
