In January, I bought a house that came with a hot tub (manufactured 2003). The previous owner said it had been sitting empty for a couple of years, but worked fine. Inside looked clean.
Filled it up, balanced the water and starting around 3 weeks it was forming a chemical smell and by 6 weeks it was unbearable (the mist from the jets would make you cough and sneeze). It was also burning through chlorine and so I got a Taylor K2006C testing kit. CC levels tested quite high (2.5).
I ran through some Ahh-some which produced a ring of gunk that looked like green toothpaste. Cleaned very thoroughly and refilled. After balancing and reheating, CC was nil.
This time around I have been adding liquid chlorine daily, but after after about 3 weeks, the chemical smell started to return, not as bad as before, but it was there. I tested and CC was showing around 0.5.
By week 4 it was again starting to cause us to cough and sneeze. CC tested at around 1.0, so I did a SLAM which after only a day and half brought CC down below 0.5, but the smell is still there. I also replaced the filter, just to be sure.
But after only another week, CC is testing above 1.0.
I'm at a loss as to what else to do. Should I SLAM it again? Run some Ahh-some through it again? Could the old filter have been bad and the new filter needs more than a week to clean it up? Something else?
