Hello, so I installed a Milwaukee ORP controller on my reef about a month ago. It took 3 days to settle with a reading of about 250. At that point I dosed Ozone once for an hour . It bumped up to 280 and the next day settled at 260. A week later I did another try of Ozone for an hour. It bumped up to 300 the the next day settled at 265. For the past 2 weeks I not added Ozone or anything and it's slowly been creeping upward. The ORP controller reads 351 this morning. Is this a concern ? I'm wondering if something is causing this which could make it continue upward to a dangerous level for the reef inhabitants I have. Thank you
