A pool renovation expert had seen it coming. Canadian specialist Steve Goodale, known as "Swimming Pool Steve," warned the Washingtonian that darker paint absorbs more sunlight, raises water temperature, and makes algae blooms inevitable.



"'If we change nothing else except the color, and we go from a lighter color to a darker color, absolutely you're going to have more prolific algae growth,'" Goodale said. "'It's a foregone conclusion.'"

"'Y'all, not to be a huge nerd but for the reflecting pool you would need a minimum of about 8,000 liters of 12% hydrogen peroxide to reach the 50 parts per million concentration to kill algae,'" Dr. Michael O'Brien, a South Carolina pediatrician, wrote on X. "Is this what happens when you have 0 scientists in your administration? 9th

[Ocelot II]

1. 8,000 liters is more than 2,000 gallons.

At this rate that's going to take awhile.

[allegorical oracle]

5. Awhile...like by the end of djt's term in office. Algae is pesky stuff. nt

[BlueWaveNeverEnd]

7. At least their not using the little bottles from walgreens

[LogDog75]

26. They're going to need bigger bottles

[PCIntern]

37. I saw what you did there

[RockRaven]

58. I count 9 boxes in that pic, looks like 4 bottles/box. So he's got a whopping 36 gal.

I'm curious what the calculation would be on how long it would take for the algae in a pool of that size and starting concentration to regrow whatever fraction of the algae population which would be destroyed/neutralized by 36 gallons. Would it even be measured in days, or just hours?

[RedWhiteBlueIsRacist]

2. How long before they put a tarp around the pool?

[Attilatheblond]

51. Desperate calls being made to Elon:

Can't you make AI that makes the pool LOOK like it's OK?

[yellowcanine]

3. Experts? We don't need no stinkin' experts!

[Attilatheblond]

52. If this regime was made into a comdey movie

AI would have a very young Mickey Rooney suggesting "I know, let's have a SHOW!"

Worst idea any American had was to create a 'reality show' where Trump pretends to be a smart businessman. That blue suit guy took it seriously and convinced a lot of really dumb people to put him in the White House so he could fire characters they didn't like.

[ShazzieB]

72. This is what I've been saying for a while.

"Worst idea any American had was to create a 'reality show' where Trump pretends to be a smart businessman. That blue suit guy took it seriously and convinced a lot of really dumb people to put him in the White House so he could fire characters they didn't like."

I absolutely agree with this. It explains so much, like why he had a ready-made base just waiting to be deployed, and why they were so ready to believe anything he said. The producers of that show had no idea what kind of monster they were creating.

[yellowcanine]

4. Everything Trump touches turns shitty.

[ProfessorGAC]

6. It's More Than The Dark Paint

The water in the pipes, sitting static, concentrated the algae.
Once the valves were opened, the first several hundred gallons of water had loads of algae that hadn't had any exposure to oxygen (bad for algae).
Since it's not soluble, diffusion doesn't apply, so those concentrated colonies has a chance to bloom wildly.
The added temperature, of course, does matter.
But, the higher temperature could have been ameliorated by the addition of about a half-gallon of hypochlorite bleach while still in the pipes.
99+% of the algae would have been dead before it went into the pond. Simple filtration makes it a non-issue.
This was done very sloppily.

[BlueWaveNeverEnd]

8. Oh..ok

[Ocelot II]

11. The algae would have come back anyhow.

Warm, still water, with duck and goose poo for fertilizer = algae. It's been a problem ever since the pool was built, and just painting the damn thing blue didn't improve anything at all.

[ProfessorGAC]

12. Agreed

It requires treatments like those used in cooling towers.
Algae in a cooling tower is death to heat transfer system (causes bad fouling), so has to be controlled and it is, tge world over.

[progressoid]

17. They could skim the algae off first and turn them into snacks...

Green snacks...?
Green crackers...?
Algae green...?

[vanlassie]

18. Trump Crackers.

It has a truthy ring to it.

[progressoid]

21. And put them in a gold bag!

[erronis]

13. I bet the maga experts didn't think about goose poo!

They are hard to avoid in the DC downtown area - tidal pools, etc.

[Dr. T]

38. Do goose-stepping ICE goons produce goose poo?

[GenThePerservering]

23. But now it will come back faster!

and be biglier!

[Attilatheblond]

54. We have the BEST algae! A big strong man, with tears in his eyes said 'Sir, how did you think to make so much algae?'

[Farmer-Rick]

19. Algae needs light to grow

Algae dies in dark pipes. I move my water for animals into underground storage during summer to prevent algae growth so rapid that it blooms immediately when I pump it into their troughs.

The brilliant pedo Trump administration pumped the new water from an open water source with algae already in it. (Perhaps the Potomac or Anacostia rivers?) And it merely grew and thrived in the extra heat.

Most algae will die in about 7 days in the dark. Some very hardy types of algae will take about 2 weeks to die. But algae does not grow or survive in dark pipes. The pool was empty for about 6 weeks. Long enough to kill most all algae.

They should consider covering it with a black out tarp. That will kill it in about 2 weeks. Though I can't imagine a blackout tarp that big.

Also a salt pool would be more environmentally safe than all the chemicals they are pouring into the pool.

This is what happens when scientists are removed from the equation.

[Ocelot II]

22. Maybe they could use the tarp from the Kennedy Center. Realistically, though,

the algae would come back. And some kinds of algae grow in salt water. There's no getting rid of algae permanently as long as you have un-aerated warm water, and you can't aerate a reflection pool if you want it to reflect.

[Farmer-Rick]

42. Yeah algea can come from the environment

From off ducks, from spores on the wind, from food dropped by animals.

But it doesn't come from dark pipes or underground storage.

Algae spores are very hardy and that's why people who don't understand photosynthesis think it comes from underground pipes. It's the spores that remain in the dark that rehabitates water once they are exposed to the right conditions.A dark bottom stagnant pool is just what they need.

Yeah there are some very resilient algaes that can thrive in salt water and without light. But it is very rare.

They should have started treatment as soon as they were done pumping. But I still think a salt pool might be the answer.

[Ocelot II]

44. It appears that algae problems are quite common in salt water pools, as well.

https://www.autopoolreel.com/blogs/news/removing-algae-in-your-salt-water-pool

Salt water isn't the solution. It's extremely corrosive and would require even more maintenance than the existing system. The electrolytic properties of dissolved salt will destroy metal components and damage stone and cement materials.

[ProfessorGAC]

49. Especially Cement/Concrete

An inorganic mechanism of metathesis exchanges the calcium ions with sodium in tge salt.
This destroys the crystal matrix because it's monovalent.
It causes bad crumbling.
As to pipes and pumps, cast iron is preferred. Stainless steel us a hard no.
The issue with pumps comes in when the system is static. Concentration gradients occur and the salt precipitates and it becomes a grinding compound for the impeller.
For some products, we had brine solutions but those had to be kept circulating. If pump maintenance was needed, those lines were drained and flushed so static periods were only fresh water.

[Farmer-Rick]

78. My brother had a saltwater pool for over a decade

He had no problems with concrete deterioration. The salinity wasn't very high and the lining of the pool was something special for salt pools.

But I've seen road salt tear up my concrete parking pad so I understand what you are saying.

And as some have pointed out, there are a lot of algae adapted to salt water. Though my brother's pool never had a problem with algae. He lived near the ocean where the spores for salt adapted algae were probably more abundant.

[Farmer-Rick]

60. The harsh chemicals used in

Swimming pools are also very corrosive.

I had no idea salt water adapted algae was so widespread. Damn it seems to be everywhere now that I'm looking for it. So, I guess using salt wouldn't solve the problem.

[Kali]

56. if you are refering to sanitizing a pool with a salt system

it is actually a chlorine system. "conventional" salt water pools use an electrolysis system to split the salt molecule and create chlorine gas which sanitizes the water. it cycles back to salt as it is used in the oxidation process. lots of algae grow in the salt water of oceans/seas etc. most seaweed is in fact algae.

[Farmer-Rick]

79. Yeah, that's what I understood

Salt pools are actually chlorine pools. Hmm, no idea seaweed is algae. I always thought all that green stuff in the ocean was seaweed, now I know it's algae too.

But the real issue is that the Park Service spokes person claimed the algae was growing in the underground pipes and that's why the reflection pond had algae. Algae has to have light to grow. It won't grow in those pipes. It's the spores that could survive and be brought in by the wind.

[ProfessorGAC]

48. Good Points

But, some algae can go dormant for more than a week.
In general though, you are correct about needing light.

[kurtyboy]

67. They should consider covering it with a black out tarp...

How well does black tarp reflect the monuments?

Instead, replace the water with a giant mirror. Do it, Mr. President!! A big, beautiful mirror, the biggest in the world!! And then you can starve to death staring at your own image like the Greek myth guy--what was his name, again? Neville? Nar-something, I think...

[FakeNoose]

32. Yes they had to flush out the pipes before filling up the pool with "fresh" water

But even the so-called fresh water would have gone green if it sits in the sun all day, and it's not moving.
Most of us know this, but almost 250 years ago Washington, DC was built on top of a swamp so ....

[calimary]

46. Maybe President Know-it-all thought cheaper was better?

[kentuck]

9. I'm no pool expert and I could have told them that...

I did have a little stream with a fish pond in my back yard at one time. The algae was a problem.

[Ocelot II]

63. Anyone who's ever had an aquarium knows that algae will take over if you let it.

Maybe the reflecting pool needs a whole lot of snails?

[tanyev]

10. Canadian? Obviously he's just saying that because he hates President Trump.

If people just respected President Trump like they should that algae never would have grown!

[The Madcap]

14. They will need to add fountains.

It won't be a reflecting pool any longer. Thanks, T****.

[3825-87867]

15. Is that what's on the back of his hand?

I thought it was from "something" else.
After all, he IS right-handed!

[wcollar]

16. Other Option

Have they tried Ivermectin yet?

[LuckyLib]

20. We don't need no stinkin experts!

[70sEraVet]

24. Has trump figured out a way to blame Joe yet?

Slow-release algae capsules, to spoil trump's birthday?

[rurallib]

25. jeez, Donnie, why not just cover it with a mirror

then you can go look at your beautiful self any time you want.

[LogDog75]

28. Are we sure the algae problem wasn't caused by

The Orange Turd taking a dip in the Reflecting Pool?

[Figarosmom]

30. Of course trumps

"Pool guy" is just a fly by night type. I bet he NEVER hires union workers for anything too.

[Norrrm]

31. But Trump is an expert. His cultists say so. Reflecting pool fixed for good.

Katie Martin, a spokeswoman for the Interior Department, said in a statement, “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. 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.”

Food source that promotes algae blooms. Pure shit.

34. Disneyland may have some experts.

Personally, I'd remake the Capital with a more natural aesthetic. The current scheme emphasizes control over nature -- implicitly setting humankind apart from nature.

If poisoning the water turns out to be the only option maybe we ought to rethink the whole thing.

[Traildogbob]

35. Algae

Is not good for the sensitive life in the water habitat, but most of these blooms takes in a mass amount of carbon.
Many Algae, not all, are photosynthetic organisms.
Maybe he is trying to be a carbon sequestration hero. Don’t tell his fossil fuel anti science Jebus freaks. We can not do good for the planet. It would prolong end of times and the trip to the sky for mansions, streets of gold and all those virgins promised.
Eutrophication feeds and creates massive blooms and Shit is a great source or this. And Washington has lots of shit everywhere. A lot of it in suits, with flags on the lapels.

43. The rapture happened back in september 2025.

Many of the ones who thought they would get raptured got left behind, and are the cause of the tribulations because of their disappointment in being left behind.

[Traildogbob]

Lots of disappointed saints. No virgins for them.
I think we should buy all the circus cannons not in use, and offer free transport to true believers.
Hurry and sign up before all the beach front Mansions with double car golden drive ways are gone. Red hats get front of the line.

[LudwigPastorius]

39. Trump will sue the company that painted it for the amount we paid that they didn't kick back to him.

"Many expert people are saying that Atlantic Industrial is fully to blame for this because of the type of coating they used. The DOJ will be taking them to court for fraud."

[Wiz Imp]

40. They really have nobody with any knowledge or intelligence in this administration.

The hydrogen peroxide will have no harmful effect on marine animals or the environment, the department said.

That is absolutely false.
https://www.dovelewis.org/blog/why-you-shouldnt-use-hydrogen-peroxide-your-pet

Hydrogen peroxide is an irritant to the digestive tract. When ingested, it can cause inflammation and irritation in the mouth, esophagus, and stomach. This can lead to discomfort, painful inflammation (esophagitis), and even long-term damage to the esophagus and other parts of the digestive system.

[RockRaven]

61. I remember when these morons were talking about hydrogen peroxide (self-administered, by mouth or inhaled) for Covid

and toxicology people had to waste time telling them "no, no, no!"

[niyad]

65. I believe it was bleach, not hydrogen peroxide.

[RockRaven]

66. Sadly, there was a "hydrogen peroxide in home nebulizer" thing. You can find articles

and blog posts about it. It was a separate episode of stupidity from the bleach thing.

Here is one such from Forbes from Oct 2021:
https://www.forbes.com/sites/brucelee/2021/10/02/stop-inhaling-hydrogen-peroxide-to-try-to-prevent-treat-covid-19-aafa-says/

Don’t hit your head repeatedly with a trash can lid. Don’t eat spaghetti and hot dogs that you randomly find splattered on the sidewalk. And don’t inhale hydrogen peroxide to try to prevent or treat Covid-19. These three things should be obvious. Nevertheless, the Asthma and Allergy Foundation of America (AAFA) has had to issue a warning about one of them. Take a wild guess as to which one.
----------
Notice the graphic of the skull on the bottle. It’s not a good idea to use anything with a skull on the bottle unless you are trying to somehow look like a skull.

That doesn’t mean that you should never use hydrogen peroxide, otherwise known as H2O2 , for anything. You can use it as a disinfectant around the house. For example, hydrogen peroxide can help clean the slobber off of your One Direction statue. It can serve as a mild antiseptic for minor cuts, scrapes, and burns on your skin. Some may use it as a mouth rinse but should seek the guidance of a doctor or dentist before doing so.

Inhaling hydrogen peroxide is a different story, though. The misinformation about Covid-19 on social media can be breathtaking. And inhaling hydrogen peroxide could take your breath away, in a bad way. It could irritate your respiratory tract right down to your lungs. Clearly, irritating your respiratory tract is not a good idea, no matter how angry you are with your lungs. Continued extensive irritation can ultimately cause longer term damage.

[GoCubsGo]

74. Actually...

Light breaks down hydrogen peroxide, which is why it comes in brown bottles at the drug store. So does organic matter (e.g., algae). It will also be diluted. There's nothing other than algae (and probably mosquito larvae) living in that pool, so it's not likely to affect any other creatures.

This is not a great solution, but it beats using algacides, which are generally highly toxic, and contain elements that don't break down, like copper. It will be a band-aid, because it doesn't address the actual causes. Until they get rid of that idiotic "flag blue" paint, this problem ain't going away.

[Goonch]

45. ;-{) THE CURE

[Jirel]

47. If you want even more fun...

It’s going to wreck the new paint and possibly the surface, depending what it’s coated with. If they plastered it, peroxide can definitely make a mess of that. They are not using enough to kill all that algae, not that it’ll help when more just keeps being added from wind, rain runoff, ducks…

They’re just dumping mass amounts around the rim. Each area will become a hot spot of chemicals, affecting the brand new bottom.

No plan and no expertise; just his gut telling Dimdonniechucklenuts that it was the uh right thing to do.

[underpants]

53. Trump is an interior and exterior designer

and horrible at both.

[Attilatheblond]

55. Is he already looking at swatches for the drapes he will order installed around that pool?

It's not like he's busy at that meeting in France where nobody will talk to him.

[underpants]

57. From what I've read he was still deeply into the design of his hotel at the Post Office

and that included looking at swatches.

That’s really all he did before The Apprentice came along.

[Wednesdays]

62. So, The Felon's minions will keep dumping hydrogen peroxide

...and the algae will still grow. All summer.

Good Lord, if you think it looks bad now, just wait a few weeks.

[Norrrm]

64. Donald had a comparison of the pool under both Obama and himself.

(Doctored of course)
Obama's pool was cruddy looking.
Donald's pool was magnificent.

Obama was not in office again so he cannot be blamed.

How did the pool look during Trump's first six months in office?

[William Gustafson]

68. here's an idea....

Take out all the water and cover the pool with durable mirrors....it will reflect and there is no Alge... just no swimming on the mirrors.... just spitting out some ideas...

And of course, everything Trump touches either dies or gets screwed up, or both....

[Raine]

69. Trump won't listen to anyone else's opinion 🙄 especially people who

actually know what they're talking about.

[IcyPeas]

70. Can he nuke algae

[Yo_Mama_Been_Loggin]

71. So much for the stable genius

[Danascot]

73. Hydrogen peroxide is H2O2

and breaks down into water and oxygen under heat or light, for example Washington DC sun on a summer day. Oxygen facilitates growth of algae, so the addition of hydrogen peroxide to the pool will contribute to the growth of more algae.

This entire misadventure is a metaphor for the trump administration.

[Trueblue Texan]

75. Algae bloom caused by warming is a Democrat HOAX!

[evemac]

76. This is a metaphor for Trump

Everything he gets his hands on turns to crap.
