If your spa has a separate booster pump or jet pump, make sure you circulate through that system as well. Repeat a few times. This will allow Spa Secret into your air blower channel also. You want to make sure that Spa Secret has fully circulated through all the pipes in the unit. This will ensure that all your pipes are sparkling clean.
Instructions Drain out the spa.
