Phosphates and pH

[AZFish1]

I read that the use of phosphate buffers will interfere with pH testing and use of the co2 chart. Will the amount of phos we dose into our tanks cause this situation as well?

Nope,
You do not need more than 2ppm PO4.
At high levels, this can influnece KH but not this low level.
