Duane Sundin
Duane…A general rule of thumb is 1/2 oz. per gallon of ordinary house hold laundry bleach is a satisfactory means of providing the desired effect in your Spa… 70 gallon = 35 oz.= 1-qt. No need to fill the tub how ever..1/2 tub = 1 pt. let circulate for 5-10 minutes, drain and flush. Happy New Year……………Bud………… Suncoast Plumbing.. Sunny Florida…
