Closed up

[Brandon3152134]

I've had this birds nest frag for about 2 months or so and it's been looking great. like 2 weeks back I did a large water change and threw off my salinity messing up my kalk dosing. Levels have been back to normal but this birds nest doesnt seem as happy as before. I have 2 theories.
1 my nutrient level dropped too low and it didnt like that
2 the alk swing has caused its growth to set back.
I have 2 other birdsnest colonies and the larger didnt show any signs of stress but the other small frag closed like this one is for about a week and is now back to normal.

The top is most recent the bottom was before the alk swing and mid is during all swing.
