So our hot tub has only what I can describe as a body odor smell. It is quite stinky.
For reference the tub is about a year old now, I changed the water once around April/may because it started to smell, it was fine for a bit, then smelled again. I thought I had maybe gunk in the lines because I forgot to use a line cleanser. So I emptied it again this time using a line cleaner chemical before and refilled. All was good. We used it for maybe 1-2 month (and went in literally once or twice), and I just went outside to check on it, smells like body odor.
I’m losing patience and ideas at this point.
The filters are clean/have been cleaned, plus they were replaced around the time I did the first refill, in April. I just replaced the Air Filter cartridge, though the previous one didn’t seem like it needed to be changed.
My chlorine is likely lower than normal because it’s one of the jacuzzis with the tru air ozone/UV bulb etc. so I would usually put two tbsp of chlorine in once a week and that was great for months, and it had lots of use.
Prior to doing the second refill and line cleanse I was dousing it with chlorinated shock, made no difference.
Is it something external? The cover? I don’t think so because if you get the water on you, the smell comes with it. I wiped down the entire interior and cover each time I did the refills with a tub safe spray. I use a shop vac to blow out whatever I could from the lines.
Any ideas?
