o.k. so I used the TFP regimen to balance my water. My FC is 5.0 and stabilizer is 70. Ph is 7.5. My spa is connected to the pool via a waterfall but can be isolated for spa only mode when using it. I fired it up Friday night and and the spa started heating. Outside temp was 45 degrees. As the spa heated, as usual, it develops a vapor discharge. The smell had a very strong distinct chlorine odor. I mean really strong. I was worried about breathing this stuff while in the spa. I tested my chlorine thinking maybe I had too much CC and needed to shock the pool; however, that wasn't the case. The FC was 5.0 as noted above and the CC was 0.0.
I never noticed this strong chlorine odor from the spa when I was keeping my FC around 3.0. Again I wanted to make sure I was following the TFP guidelines.
Appreciate any insight. Should I be worried about the odor and breathing the fumes? It was a bit disconcerting.
