Stability is one of the most important things you can establish with a marine tank. Anemone is likely upset.
With tearing tank down, you have literally placed tank in start over mode.
Add 1ml of liquid bacteria to tank over the next two weeks.
Hopefully you have reliable test kits and not API to monitor water
Not not move the anemone any more. Provide moderate light and water flow and the anemone will do the rest
