Welcome to our forum.
I do have the ozone system, still 89 and going on 36 hours. Guess im just impatient. When it was 70 degrees me and my roommate hopped in wearing some waders. man im a redneck.
Tubs now up to 92. Before i went to bed last night at 6 am i reset the tub. seems like its making more progress since, any ideas if that would make a difference?
