How with dinoflagellates and cyanobacteria?

I would caution against doseing high amounts of phosphate. Because imagine being an montipora or an acropora in that aquarium. The host ( Us ) drops in a stiff dose then in an hour or two it zero again. Repeat this for a extended period of time. These animals need stability. That is a nutrient roller coaster. But I’m still learning .

I personally don't think that is likely to be a problem.
