I bought this chemical kit for my Jacuzzi that has everything that you need to take care of the water and it turns out I don't need it cuz my jacuzzi has a thing in it that keeps the water clean automatically. All the chemicals are unopened and untouched I paid $125 I'm asking $90 for it and I also have a digital water tester that makes it easier to test the water that I paid $40 for and I'm asking $20 for that
