The reflecting pool turned green within just a few days after the repairs were completed. One report said the algae returned after “just a few days,” and another described the pool turning green shortly after reopening.

What the reports say

  • The renovation was finished last week, and the green algae showed up almost immediately afterward.
  • Coverage from the same period says workers were already cleaning algae from the pool shortly after reopening.
  • A few outlets described the change as happening “days after” the costly renovation.

Quick scoop

So the practical answer is: not long at all — only a few days before it turned green again.

TL;DR: It lasted only a few days after repairs before the water turned green again.
