i just moved into a new home and it have a hot tub, what do i need do to get it up and running?
Answers:    Its not ominous, turn off the heather and pump, drain it if it still has river, clean it out, check the filters. Fill it fund up and turn back on the pump and heater. You can put the chemicals within then or when the water is hot, in attendance will be instructions on how much to enter.
You didn't say what kind of hot tub it is? If you know the identify of it it might be wise to contact the manufacturer for a instruction book .
