What it looks like now

From what I noticed right away. The zoas are stretching towards the light. Meaning, they aren’t getting enough light to grow but merely survive.
The hammer is gone, probably from starvation due to the lack of light and 0 nitrates.
Algae is taking over possibly due to no nutrients and the algae is consuming what little there is and starving the corals.
