Have you measured your PAR? What light is that and how long do you run it?

I have not tested my Par yet. I run the light for about 6-8 hours.

you should bring your salinity up. to 1.025-1.027 ideally. It’s most important aspect to the reef tank. "Feed more". As your nitrate was at 20 but now zero. which means either your tank filtrations are too good or you not feeding enough. this is general idea since i cant tell what you got in there as livestock and size of the tank. You can also use pre-formulated solutions you can buy or make your own solutions to bring those numbers up.
