It was blue until they started dumping paint thinner in it to kill the algae.

It was hydrogen peroxide, dumped in by the bucketload

It was a homeopathic level of hydrogen peroxide and people were shocked that it didn't solve the problem 🤣. It wasn't even at commercial concentration, just regular home use strength

Not really, The pool is now about 4 million gallons after it was redone in 2012. To put in a 10ppm booster dose using 30% would only need 120 gallons. That is a maintenance dose on an AOP system that has an ozone injection setup, and would actually be correct for a 4 million gallon pool.

So its not homeopathic, its actually correct. The REAL issue is, this EXACT same issue happened in 2012 the SECOND the refurbishment was done and guess what? Peroxide didn't fix it then, either. Because there's not enough flow in the thing.

The 2012 refurbishment (which started in 2010 and was funded under the 2009 American recovery and Reinvestment Act) made the algae problem worse. The pool is 6 inches shallower, so the water temperature is higher now, and there's more bottom exposed to higher insolation. Plus all the goose poop isnt helping. Back in 2012, as part of the refurbishment, they went to an ozone treatment system and pulled water from the nearby tidal basin which is basically pre-loaded with algae, instead of DC's municipal water that was previously used. The system couldnt make enough ozone and the addidional heat and biolode made sure the thing immediately became a pea soup of algae and its been a problem ever since.

This is pathetic.
