Dude I've been having a shitty day and this comment has got me laughing so hard. Thanks for the pick-me-up.

Actual the alge is in the water source. DC is a swamp. (in more than one way.) The pool needs to be removed. No one cares about a vanity pool that is a gaint tax sink.

Only if he tells them to

It's really big and shallow, so without juat turning it into a toxic mess, it's probably also not that easy. The problem is spending 14 million dollars in tax money to "fix" it, while making it worse. I swear they only do this shit so americans get so used to these high numbers so they don't revolt. 14 millions here 300 billions there, don't worry, if you work long and hard enough, you can afford 3 eggs

Sounds dumb, but since the water source is a literal swamp and it's an open loop, there's really not much they can do besides clean it frequently. It`s just going to keep pulling water from the swamp anyway.

I mean they could tear it up and make it a really nice green space, but we can't really expect that to happen.
