Why is 24hr ozone any more effective than the regular pump occassionally running keeping up temp running through the ozone filter?
Both methods are fine for filtering but when comparing the two I like the circ pump idea for other reasons. It is a bit of a cost saver (not major) but more importanatly to me, it allows for 24 hr ozone and is much quieter.
Or you could look at a spa that does both...circ pump and filter cycles...such as sundance/jacuzzi premium.
It's important because ozone is a toxic gas that can be harmful over prolonged periods of exposure.
