Well, you only get 7ppb residual under ideal conditions (100% mass transfer, perfect ozone production, etc.). Realistically I think only a few parts per billion. Hard to imagine that little even causes "supplemental off-line oxidation", but perhaps smaller localized concentrations have useful...

Regarding Nitrates increasing chlorine consumption, I was assuming the algae would eat the nitrates and then the chlorine would be consumed dealing with the ensuing bloom :wink: Where do you get this? My research suggests the half-life is only a few minutes (5?) at 40C. If the presence of...

These ambient air CD units also produce lots of Nitric Acid (highly corrosive), Nitric Oxide (poison gas) other Nitrous byproducts, and even Nitrates (Algae Food). Maybe the Nitrate production explains the increased chlorine demand with no bather load. Ambient air CD units also suffer reduced...

Well, my nose correlates well with my safety monitor: EcoSensors C-30ZX, which is installed in my pool equipment room. When the ozone destruct units are not functioning, lots of O3 can build up near the generator. I still find it difficult to believe that UV based spa ozonators cause any O3 to...

Okay, fair enough, if there is a higher concentration of ozone dissolved in the water than there is in the surrounding air, it will outgas. That is how we got it to dissolve in the first place, right? Putting bubbles with a high concentration of ozone in the water. However, I believe surface...

Sorry, I meant to say Bromate. I refer you to this thread http://www.troublefreepool.com/will-bromine-used-with-ozone-create-carcinogens-t24905.html regarding its carcinogenic properties in a pool/spa. Chem Geek seemed convinced of its safety. Still, you don't want to mess around with...

Jason, its important to understand that there are two types of Ozone at work. Gaseous ozone and Dissolved ozone. Both are excellent sanitizers. Gaseous ozone is toxic, but dissolved is not. The air-water separator and ozone destruct unit remove the gaseous ozone from the water before it is...

I have an ozone pool which has been running very well for about 5 months now. I have two very large (22gm/hr) units and do not use supplemental sanitizer (yet). The pool is covered almost all the time and has very low phosphate levels (~300ppb). I have not had any algae problems and the water...
