A little update... I transfer tanks from a 12g cube to 24g, finally got my ATO to work properly so there should be no fluctuation in salinity. Fixed my heater as I had the on/off too far apart via apex. Also, did a acclimation to the AI light. It's looking better and finally opening up with a tight mouth during the day, but still gapping at night if it isn't closed up. But, it did reattach itself to the rock, as it looked like it was starting to detach about a week ago.
Also, added a IM fuge light and going to get some clean chaeto (waiting for it to arrive), so that should help with my PH fluctuations at night as well. *hopefully*
I'm looking forward To see what this wonderful nem turns into if it recovers!
