Welcome to our forum.
I also use a chlorine solution that involves me throwing in a pre-measured dissolvable packet after each use, or every couple of days.
not heard of this at all,I would worry about dissolvable packets residue sticking to filters
And if so, do I need to drain the brominated water and start fresh with Chlorine?thanks,Tony P
I changed from bromine to chlorine and am very happy with it. Read my post bromine v chlorine http://www.whatsthebest-hottub.com/forum/index.php/topic,15711.0.html
I'm not an expert, so someone else verify this, but you do not want to mix chlorine and bromine. You may even have to flush the lines first. Again, I'm not expert. Someone else should weigh in on this.
There is no problem using chlorine to activate more bromine in a bromine spa. It's just that once you have converted a spa to bromine, you can't go back to chlorine without a water change. Any chlorine you add will convert bromide to bromine.
