1 of the good things about the Enaly is that it took almost a month for the ORP level to go from 284mv (before the O3) to 380mv (current level). This ensured that the inhabitants did not stress. No matter what unit you use to create the O3, it is documented that you should not raise more then 20mv per day initially. So far the Enaly is doing the trick at a very inexpensive price. Only time will tell if the unit last as long as the pricier units out there. After all, its just a corona (without the lemon) that has air passing through it. That's like air passing through the filaments of a very, very, very bright light bulb.
In fact, Corona is the ionization of the nitrogen in the air, caused by an intense electrical field. Electrical corona can be distinguished from arcing in that corona starts and stops at essentially the same voltage and is invisible during the day and requires darkness to see at night. Arcing starts at a voltage and stops at a voltage about 50% lower and is visible to the naked eye day or night if the gap is large enough (about 5/8" at 3500 volts). Corona produces sound, nitric acid (in the presence of moisture), ozone, and ultraviolet light.
