So the last few nights after using the hot tub, i've added roughly 2 oz of 10.6% liquid chlorine per person (roughly stayed in 1/2 hour). the next night before using, i check and seems chlorine is done to 0. I add about 2.5 oz (~475 gallon tub) prior to use so as to bring up chlorine.
Last night 15 min prior to use i added the 2.5oz of liquid chlorine and 22ml of MPS. Then again after use added 2 oz per person.
6 people in tub.
So i will be interested tonight to see if there is any residual chlorine.
it is a brand new tub, only used 3 nights now. Used Ahh-some prior to setup, so everything should be clean.
Added Spa Marvel as well, so thought that would perhaps assist in not using up the chlorine as quick.
Hoped there would be at least 1 ppm of chlorine left.
