Bulky nanobubbler machines were carted off ahead of a promotional event for President Trumps Ultimate Fighting Championship birthday party.

Dotted around the perimeter of the memorials Reflecting Pool were the nanobubblers, the temporary water-purification machines meant to keep the pool clear of algae. Encased in black fencing and powered by large generators, the machines were something of an eyesore.
Before the event, the National Park Service asked Greenwater Services, which won a $1.7 million no-bid contract to install the nanobubblers, to remove them, according to two people briefed on the decision. The people asked for anonymity because they feared retaliation from the administration. The Park Service did not provide a reason for the removal, but it coincided exactly with the promotional event, which drew crowds to the Reflecting Pool.
Photos from that evening showed the pool without the hoses or enormous machines working to keep the water clean. The water looked dark blue.
But by the time the purification systems were reinstalled 36 hours later, enormous algae blooms were starting to spread unchecked, turning the water green.,,,,,
The decision to remove the water-treatment systems, which has not previously been reported, was one of several missteps that have plagued Mr. Trumps $16.4 million renovation of the Reflecting Pool. There have been no-bid contracts, peeling strips of waterproof coating in Mr. Trumps handpicked shade of American flag blue, and even a dead duck floating in the water (though it is not clear if the renovation had anything to do with the ducks demise).
