Newly renovated Reflecting Pool is already fighting an old problem

President Trump wanted the Lincoln Memorial Reflecting Pool looking its best in time for America's 250th birthday celebration

The problem? Just days after a multi-million dollar makeover, the water has turned green

Workers were back in the water this week trying to get a handle on an algae bloom that appeared less than two weeks after the reflecting pool reopened

The Trump administration spent more than $14 million on the project, fixing leaks, installing a new filtration system, even painting the bottom what the president called American flag blue

We made the surface as good as it can be, and we're now covering it with the most beautiful blue

Very thick, you think of it as a very sophisticated form of rubber

No leaks, no problems. And it's beautiful. It's called American flag blue

that was the color we chose. But now instead of crystal clear reflections

visitors are seeing patches of green algae spreading across the water To fight it crews have been vacuuming the pool running a high filtration system and adding hydrogen peroxide to the water I glad they trying but honestly

I don't think you can fight mother nature. And the nature of this pool, anytime you have an

environment that big, that's like cleaning a lake or something else. As long as it doesn't stink

I'm okay and as long as I can enjoy it and get close I'm fine with it and happy about it

Experts say the shallow warm water creates ideal conditions for algae and warn this may be more of

an ongoing maintenance challenge than a one-time fix. Some visitors are not impressed. Absolutely

it was 100% waste of funds. I do however see that the National Park Service is getting some work

today, clearing out the algae. To be fair, algae has plagued the reflecting pool for decades

including after a $34 million renovation during the Obama administration. The question now is whether this latest high-tech fix can succeed where others have struggled
