Temporary high phosphates for SPS?

[Reef Pilot]

Wow, am surprised at how high temps the corals and fish can handle. My downstairs tank has only LPS and softies, no SPS, so am less concerned about the corals.

But because my SPS has been doing so well in my main upstairs tank, that's where my biggest concern is, if the P04 jumps up when I combine the tanks.

Thanks everyone for the feedback. I will take it day by day, and see what happens.
