The water in every spa circulates when the spa is being used and when it filters ( and circulates constantly if the spa has a 24/7 circ pump) and, added at a rate of about 1/2 cup to 300 gallons of water, is VERY diluted. Plus, spa owners should be monitoring their pH to make sure it doesn't get too low. Based on this info., I would not be concerned about stainless jets corroding.

Well thank you for informing me better.I am about a week from reciving my new tub and was a bit concerned cause i too ordered stainless jets. To me the stainless jets help make your tub look luxurious, and with what tubs cost i want some bling baby. all my serching i heard nothing of stainless coroding.it may not be a real threat but its good to know it could happen if my levels arnt monitored ,and that my circ pump will help prevent it too.
