Honestly? I would have no problem with maintenance. Even if it wasn't strictly necessary, but could do some good, there wouldn't be much reason to complain at all. The problem certainly isn't in the "if it ain't broken" part, though the pool had serious issues that were worth trying to fix. The "don't break it" part feels like it's underselling what went on, though.
The problem was and is in the extreme corruption, irresponsibility, incompetence, toxic propaganda, and so on that have been integral in every step that the Trump Administration took. All this hubbub about the algae may be fun and easy to mock and meme and is embarrassing to them, but it's also just a result and not really the real problem.
I'm going to have to object, again. Complaints about zero integrity in this administration and in the Republican Party in general are well warranted, yes. In the country? Not so well warranted. The Democratic Party has consistently and actively worked to uphold the trustworthiness and integrity of the government.
We certainly deserve to take a very real hit and much mockery because of the Republican Party, but there's little value in accepting bothsiderism, whatever the form.
Adding to that - a tiny, vulnerable minority. The Republican Party largely acts like bullies when it comes to who they go after, either way. They're the stealing candy from a baby while mocking the baby crowd, politically speaking.
Correction - partially back. His fixes tend to be very incomplete in practice.
