Do not use Bromine Tablets or floating despensros in your spa or swim spa as it will damage your spa which is not covered under warranty.Some people buy bromine tablets to put in a floating dispenser or ‘floater’ in their spa. We do not advise doing this, as it tends to concentrate the bromine on the surface of the spa’s water and can damage the acrylic shell around the spa’s water line, damage which is not typically covered under the spa warranty. It can also harm jets, headrests and heaters.
