Hi All,
We picked up a used Swim Spa and converted it to run on propane so we can run it year round in Connecticut. The kids love it. We have had two hot tubs in the past, one Cholrine the other bromine, and they worked fine, enough.
Fast forward to this 2,500 gal tub, I'm having a hard time keeping the pH down, adding MA 31.45% twice a week aiming to get a pH of 7.0 to get the TA down - and its been working, we are at 110 down from 210ppm a month ago after the initial fill. First question - is this normal? it feels like a lot of acid, ive been second guessing myself if theres something left over from the "swim spa" heater that could be causing the pH to climb back up?
I've been supplementing with liquid chlorine while I dial in the SWG, and when the water has gotten a little hazy, bc the FC was low (at one point it was 0 because I forgot to turn the timer back on) it would clear up overnight with LC. I just did a test and FC is still over 5, for but the water is a little hazy.
The tub gets used about 2 hours a day, the rest of the time its covered with a standard heavy insulated spa cover. I flushed the tub with bleach and water after doing the conversion to propane and salt with 500 gallons of clean water, ran the jets and everything for a few days before pumping it out and having it filled. Haven't had to add more water in the 6 weeks its been used but rain water does get in from between the two covers.
Second question- aside from the MA and LC is there anything else I can do to clear up the water? does having the temperature at 95-99 have any effect on this?
Thank you for all your help!
George
