I have a Sundance Optima (about 500 gallons) Hot Tub which I won't use during the Winter. Last year I kept the water in the tub and when Spring came the water was scummy & discolored and the spa needed a good cleaning.
I was thinking of emptying it this year and was wondering if there are special instructions on how to prepare the spa for Winter. Or should I simply leave the water in the spa but be sure to manage the chemical levels over the Winter?. I live in Central, New Jersey.
Any comments or suggestions will be appreciated.
Thanks,
Sy
