Welcome to our forum.
Here is opinion piece regarding the bromine vs chlorine question. I found it easy to understand. But if course, you will decide what is right for you. http://www.hottubworks.com/blog/bromine-vs-chlorine-for-spas-hot-tubs/
I never used bromine but from what I've seen many people use chlorine without any issues.It is easy and if you can time the dosing you can soak in little to no chlorine. But chlorine is not automatic like putting a bromine feeder and if you leave the tub for any length of time will get funky. But with that being said I have left my tub for a week or two while on vacation to no ill effects. One common newbie mistake is trying to keep chlorine levels at 3 ppm all the time.You an try chlorine and if it doesn't work out you can convert back to bromine without draining the tub.
"Opinion piece"? On a retailers website, you you think there's no bias? Since they start off talking about trichlor, which should NEVER be used in a hot tub, one can easily surmise that the rest of the article is filled with many more "inaccuracies".
So enlighten us rather than generalize and hint at inaccuracies? Because just about every other source I find via Google reaches the same conclusion that linked article does... Bromine for spas, Chlorine for pools. And yes, I'm sure this has been covered over and over but for the searches I have done here, it's usually "Do it this way because that's how I do it"Main points being Bromine works better at higher temps and higher ph levels typical in a spa. Also Ozonators compliment bromine better.Though it does seem Dichlor is the more popular option around here and I'm not sure why?
I know that some people were experimenting with hydrogen peroxide and I don't know how that all turned out.
