I have noticed some of my acros have started to lose color at the tips and even stn. I have recently switched to a calcium reactor and my alk has not been perfectly stable but never more than a 1dkh swing from where is supposed to be which is 8.5dhk. I have been focusing so much on alk that somehow my salinity has crept down from 35ppt to 34ppt I am assuming this would also have had effects on alk? I am bringing it back up by adding salt water to my ATO but is surprising how much is need to increase by 1ppt in a 350L tank. So far I have only managed to increase by 0.1.
I am wondering if this is likely the cause of the stn or if it could be a delayed reaction to a minor alk swing when my calcium reactor stopped dosing over night once or a combination of both.
