Choosing the right spa supplies depends largely on what your spa is equipped with right now; if your spa is new, you will probably need all these products, while an established spa may only need a few items. Spa filters, vacuums and thermometers are an absolute necessity, while spa aromatherapy products and cover lifters will simply make your life easier. Spa covers of some sort are necessary, but you don't need to select an expensive all-weather cover. A simple and affordable solar cover will protect your spa from UV rays and light rain, minimizing the amount of balancing you have to perform. Any product under the spa supplies umbrella will make keeping your spa running at it best with less effort, giving your more time to enjoy your spa.
