Cyanobacteria but with good results??

Hi everyone. So my wb 65.4 8 months old
Salinity 1.026. Temp 78-79
Checked today nitrates 10ppm phosphate .03
But I do get some cyano growth
Oh rodi 7 stage at one point was 1tds but only for a month otherwise usually zero.
so is the cyano consuming more nutrients than I can test? What do ya think
