My wife and I bought a home with a hot tub. Its a 6 person @home tub outside. As part of the home purchase they sent out a guy to drain it and refill it. He did not really help me in understanding what to do. It has been about 6 months and I will in the next few weeks drain it and refill it. I know how to clean the filter. I use Bromine as a sanitizer. I bought 2oz packets of leisure time sodium bromine as the initial treatment and Have the tabs for slow release. I also bought the Spa Essentials Spa Shock Xtra 2 lbs to use as needed. So any help in getting started and a program would be appreciated.
