White bugs on acros (not red bugs)

I have been trying to color up my acros for the last few months with some acros are very healthy and have great PE, coloration while other are looking very sickly and have not had PE in the last 6 months.
Parameters are
SG: 1.026
Alk: 8.26 dKH
Ca: 475
Mg: 1250
NO3: 1-2
PO4: 0.05
Temp 78.4-78.8

10-15g WC weekly on a 130g system
402w T5 lighting

PO4 was high and have gotten it lower and the corals have gotten better coloration but not as much as I had hoped.
In the last week I have noticed tiny white bugs crawling on most of my acros and the acros that are most heavily infected are the unhappy corals with hardly any to 0 PE. These are not red/yellow/orange bugs or black. They are white and look mostly like copepods. They are very small and move quite quickly and are much less than 1mm in size. One of the colonies that's the most infected even has an acro crab (not a gorilla) so I assume these bugs are even too small for him to grab. I'll be grabbing bayer to dip all the corals. Has anyone ever seen these white bugs on their acros? Upon first glance they look almost like mesanterial filaments beginning to come out but they are not.

Heres some photos of the pesky bugs. They dont seem to do damage but Im sure they are stressing out the corals a lot.
