I recently moved into a house where the previous owner used biguanide in the spa. We are having a coughing issue with fumes when the spa jets are on (surprisingly we don’t have the goo issue people talking about). I didn’t have the fume/coughing issue with bromine in my previous spa ownership experience. How do I go about switching to bromine correctly? I read that I should use ahh-some and drain the spa but do I just do this one time or do I have to repeat the process several times? I recently got new filters but used them with biguanide, so can I just clean them and reuse with bromine or do I need new filters again?
