Alkalinity is a little low, but probably not the main culprit. But I’d be more concerned about the phosphate. 0.5 is definitely enough to make corals unhappy.
what do I do to rectify this?
Phosphate reactor with GFO is most common. You could also try lanthanum chloride - some people swear by it, though others are scared of it. Definitely want to read up on that before trying.
