Ozone report...
After running my unit for about 3 months I always ran about 400-410 mv. My controller would shut it off about 390 mv.
This was the norm and I could see my tank was always crystal clear, even at an angle bottom to top.
Now, since the last 3 weeks I've seen my ozone unit never shut off and been gradually comming down to 350 and 325 mv.
Today I get about 320 mv; the water still looks clear but not as clear as when I use to get while at 415 mv.
So I call Milwaukee to order calibration liquid and they tell me if I'm seeing numbers in the norm, the unit is working; it's when you get readings in 500 + or 100 - that you have a faulty probe. Nevertheless, I'm awaiting my calibration liquid.
The only difference that I see, is that I have been running a UV unit 24/7 since I fought and won a massive ich outbreak. Could that be one reason my ORP has dropped to that number and will not climb past that?
I also just recently started AZ-N03 absolute zero Nitrate remover in an attempt to bring down my nitrate from 20ppm to 0ppm.
Just want to share this with all of you; oh yeah I'm running a T line to my Sanders ozonizer and I run 50 mg/hr inside a Deltec AP600.
I'm also finally ready to bake my beads they are exhausted; I'm using the 500 g from RedSea.
Any guesses??
