Boy did I screw up. I noticed my alk was creeping up a little so I turned off the pump that doses my alk for a little while to let it come down a little until i had time to adjust my dosing on my Apex. I wasn't paying attention when I turned it back on and I set it to "on" instead of "auto". It dosed constantly for 23hrs. My alk went from 10.4 to 14.84. I'm making water now for a water change and I turned off the dosing pump. However I don't want to lower it too quickly as I think one abrupt swing is enough.
