It’s part of the normal startup process. We are removing the algae, and the nanobubblers will maintain the pool and keep it algae-free,” communications director Kate Martin said in a statement.
Grant Stinchfield thinks the algae along the edges of the Reflecting Pool is the result of sabotage. That doesn’t appear to be the case. This is only a temporary condition. The President oversaw the installation of a new filtration system to address the algae issue. The algae we see is residual from the pipes that were lying dormant for eight weeks during the repair process. It is a normal part of the restarting process.
President Trump fixes the reflecting pool and a week later it’s green again, loaded with algae… Sabotage… Vandalism? I believe it is. The left can’t stand Trump, American greatness and his quest to make DC beautiful again. What a shame! pic.twitter.com/ohvldLLgZL

The reflecting pool received a $14 million renovation completed in early June 2026 under the Trump administration. Residual algae from supply lines dormant during the 8-week work appeared upon refilling, a normal restart issue now being addressed with new filtration systems.
An Interior Department spokesperson said the algae is “residual” and a normal part of the early process of restarting operations at the Reflecting Pool.
“What you are seeing is residual algae from the supply lines, which have been sitting dormant for eight weeks while construction has been taking place. It’s part of the normal startup process. We are removing the algae, and the nanobubblers will maintain the pool and keep it algae-free,” communications director Kate Martin said in a statement.
“President Donald J. Trump is an expert builder who has fixed the Reflecting Pool for good, unlike the failed and extremely costly attempt by Obama and Biden,” she added.
Martin said that the National Park Service invested in “a state-of-the-art ozone nanobubbler filtration system” that is intended to keep algae out.
