Safety of Methanesulfonic Acid to Lower PH in Hot Tub
CanadianSpaTech:
Could be bacteria in the plumbing lines. Google "hot tub lung". I would run a product called Ahh-Some through it and wipe all the surfaces down then re-fill. Super chlorinate it with spa shock using clean filters and let it run for a day then and do it all again a second time cleaning filters before and after. Also soak the filters in Ahh-some filter wash for 24 hours and clean them thoroughly or even replace them all together. Personally I would not use it until all this has been done.
HotTubLung:
Thank you for the advice. I will definently run a pipe cleaner through the tub and replace the filter again. However, I am almost certain that wasn't what caused the irritation it's a required maintenance item coming up soon anyway.
Do you have any experience using the MSA product? I haven't been able to find any information on it anywhere.
Also, I notice in another thread that you're a spa tech. What part of Ontario do you service? I have been looking for a person/company to help with maintaining my spa on a weekly basis and for minor repairs.
Thanks
CanadianSpaTech:
Halton Region. Never heard of MSA. Not a good time for respiratory issues. Have you contacted medical advice? Why are you almost certain it is not bacterial related and connected to this product?
HotTubLung:
Yes, definitely not a good time for this. I have received advice and it's 99% unlikely related to the virus. Normally I'd get some tests done, but hospitals are the most dangerous place to be at the moment, so hopefully the respiratory issues resolve on their own after weeks or possibly months.
The reason I know its chemical related and not from bacteria is that I had just spent hours in the hot tub the day before I thoroughly cleaned it and had zero issues. The breathing difficulty came immediately after being in the tub for 30 mins. Another sign it's not virus related as well.
I did have concerns the chlorine was high even though it read around the 4ppm range, so I kept the jets off for most of the soak. When I did turn them on at the end of the 30 min session I immediately begin to cough and feel irritation in my throat and chest and exited the hot tub immediately.
The symptoms now are shortness of breath and irritation/burning in the sinus area, especially when outside in the cold. It seems whatever chemicals were off caused some sort of burn to my entire respiratory tract. Fun times....... Hot tubs can be dangerous.
