I am still in shock that my Ozone really only needed one hour to recover the ORP reading of 400. I got up this morning and it is now 450 and the unit is set for 400. The probe is clean no slime on it. It was going to about 425 on its own before i tried the new salt.

FWIW, that may not be a benefit. A little hypochlorite in the mix would drive ORP up. Would that be good? Maybe it is just a little ferric chloride or a high oxidation state of manganese. Whatever. I'm certainly not saying they do any of these intentionally, but high ORP in a raw salt mix is not necessarily preferred, IMO.
