I truly enjoy the clean and odorless feeling that Silk Balance has given me since switching over from the weekly use of several different chemicals. My weekly spa maintenance has literally been cut by 2/3 the time. I no longer have to measure the PH levels or be concerned with shocking the spa with a boat load of chlorine to clear the water. I simply clean my filter and add 3 oz of Silk Balance and close the cover. Its that simple! I’m glad a made the switch and would recommend Silk Balance to everyone. Thank you, Mark
