Congratulations, it looks like you went the right direction by adding ozone to your tank. Although with a skimmer like yours, who needs ozone . I checked out the unit that you are using, and it's gotten great reviews. Are you using the unit with the built-in controller, or are you using an external controller? Red Sea also sells a unit with an ORP probe, or you can choose to get one separately (like a PinPoint) and attach it to the Red Sea unit. Which route did you take and why (if you don't mind me asking). I'm really interested in ozone, but I'm a little leary since I have a mixed reef and if the water is "too clean" then my softies might suffer (?).
Your ORP has been steadily rising and your pH hasn't budged ... guess my theory about the partial pressure of CO2 and an expected alkalosis wasn't correct afterall dontknow.gif .
