Should I dose or not?

[moz71]

So I have always had lower phosphate. Hovering up and down from .01 and .06ppm. And past 6 months nitrates around 20ppm. Which I have been completely fine with. But latestest testing phosphate at zero and nitrates at 5 ppm. And have not done anything different except dose some minor elements (Redsea colors ABCD). To help low minor elements. I did notice cheato started growing more which could be reason. I have dosed nopox consistently for over a year. Should I do anything like dose phosphate? Don’t want an immediate reaction or should I let go couple days to see if things come back to normal?

I’d feed more or dose phosphate. The trace elements may have spurred growth, hence a reduction in nutrients.
