I'm really not sure what I am doing wrong here but for some reason this year when the jets run in our hot tub it causes everyone to cough.
Although my numbers aren't perfect they don't seem to be that far off.
Any one have any ideas on what I am doing wrong? And how to fix this?
PH 8 (this is always on the high side)
The only thing different we did this year was add salt. I'm not sure of the level but I know it is not that high.
