To what degree is a phosphate spike harmful to LPS?

[lx_Reef]

Iv been very curios to see to what degree is a phosphate spike or slight rise harmful to corals mainly LPS. I see many tanks fluctuating between 0.05 to 0.10 for example and never really have a solid stable PO4 value. I know stability is what we all try to achieve but in the end is that slight fluctuation enough to tick things off? Or do we really need a huge spike to tick things off maybe going from 0.05 to 0.30?

My tank is mostly LPS and I've had my tank go from 0.03 to 0.35 phosphate in a couple of days in either direction and have never really noticed anything to any of them.

I'm less concerned about LPS.

Acropora on the other hand can start to RTN.
