I purchased a Beachcomber hot tub model 321 last summer (2010) and honestly I am disappointed and open to your suggestions.
First of all, it is noisy 24/7 non stop, I can hear the motor from the upstairs bedroom when the window is open, no fun .
Also, even though only one or two people use it, after showering, the water is not completely clear. I check the pH every 2-3 days and adjust when it gets too low, use 1 tablet of Bromine once a week, shock it once a week, always keep it covered. What else can I do?
