    Our SpaGaurd Water Balancing Kit is a bundle of the 3 most important and commonly used water balancers. Using water balancers is important for protecting your spa equipment, especially if you have an electric cold plunge tub. We strongly recommend this product for all our customers running electric heating systems, as these products help prevent equipment and surface corrosion and damage due to improper water levels.

    Our SpaGaurd bromine spa cleaning kit is perfect for keeping your water fresh and safe. We recommend bromine as a gentler alternative to chlorine. Bromine is an ideal choice for families with children who use the tub regularly. Bromine does not have the same strong smell as chlorine and is less abrasive on your skin, making it a very popular choice with our customers.
