It's interesting that most the public think all hot tubs are the same. Since my friends know that I work for Bullfrog Spas they always bring their hot tub questions to me, most not even knowing what tub they own! So here is the latest. My "buddy" has a hotspring that he loves, but out of the heater he is getting a black soot like stuff. Never had that problem before. I asked what he has changed lately and he has switched his tub from bromine to blue juice.
Have any of you hotspring guru's heard of anything like this...I assume its the change in sanitizer, but have never seen anything like this before. Any help to make me look like the "end all be all" would be appreciated.
Thanks
