I wanted to share this update with all of you.
I used sodium bisulfate, followed by a 15% water change to lower my alk. Now my alk sits at 8.1 dkh.
However, this dropped by pH to 7.3. I do not have a protein skimmer, but I have a refugium. I decided to add an airstone to my sump's filter socks chamber and aerated with indoor air. pH did not climb above 7.4 after close to 48 hours of this.
I then routed my air intake to take outside air. The pH is currently sitting at 8.0 (slightly above, I used API for pH) after 12+ hours of outside air. I am so excited about this.
However, I have noticed that my heater is working all the time now. I moved the heater and the thermometer to opposite ends of the display tank before adding the airstone. My tank temp is consistently at 78f despite my heater working all the time.
Should I be worried about the heater overworking? The outside temp is between the high 50s to low 30s.
