I heard phosban works well with these guys. Caused by excess nutrients I believe. Know anyone close with a phosphate testkit?
I'd personally be worried about my corals in a lights-off situation. Might be worth it to try for a day or two days. take a before and and after photo and see if there is any difference.
All your tests look fine to me. I'm about 95% sure that its a water quality issue unfortunatly.
