Just got my deluxe and set it up today. My initial orp reading at about 8:00 a.m. was 27 (which I thougt was very low). I have the ozone set to 20 which I know is low for 125 gallons but I figured it is always good to err on the low side. It is now 11:00 and my orp is reading 78, so it is slowly rising. My question is, could my orp be this low? Maybe a faulty probe?
