that's odd...you went from roughly a 7 or 8 dkh (converted) to 17?
Then you didn't dial in the reactor. I would take it off line and wait to hook it back up until you have a good grasp on how it works. You need to adjust the pH and effluent rate so that it maintains your alk and calcium levels. You had it set to deliver too much and it increased your levels over time stressing out all your corals.No I never tested for alk while I was failing in the reactor
