It’s a matter of long-term economic effect. Both work, but one is cheaper in the long-term because bromide sanitizers for longer at higher temperatures, such as those which exist in hot tubs. That’s the point they were making.
Chlorine also works fine, but because of the higher temperatures, you have to use more, which cost more.
Bev would say no, because it’s not green and saucy enough, but it’s unclear what Tom Paris would think. He might prefer the traditional Dickens (ref: Fair Haven), but might also gravitate towards the cheesy Bill Murray “Scrooged” (a la Capt. Proton).
I’m gonna have to say that Tom Parris would go for the Dickensian version, just because he prefers the long play, especially considering his character growth through the series. However, it might still be a bit more goofy than one would traditionally expect.
The show was made for syndication, so it wasn’t airing on any particular network. It was Rick Berman that had the issue with it on Deep Space 9, and both he and Brannon Braga (aka “Bermaga”) that had an issue with it on Voyager and TNG. Both of them are known homophobes. 
But even what happened with Ellen in 1995 and Will and Grace in 1997, didn’t make much progress on Star Trek. There was even a scene with lieutenant Hawk and his husband in Star Trek first contact that was cut per Rick Berman‘s orders. 
edit: sorry for the multiple replies! lemmy is being weird
Ira Stephen Behr and Ronald D. Moore later lamented that they didn’t push back harder against Berman and other producers for queer representation on DS9 in the DS9 documentary What We Left Behind. They notably had tried in the beginning with Garak and Bashir and were immediately shut down.
Behr, in particular, really felt bad about it.
Edit: Andy Robinson, who played Garak, had a real “fuck you” attitude about that and continued to play Garak as “omnisexual” anyway. There are little hints and innuendos throughout the entire entire series between him and Dr. Bashir.
