BioGuard Symmetry 750g

BioGuard Spa Symmetry can be used in automatic feeders or floaters for sanitising spas. When used as directed, its slow, consistent dissolving rate provides a constant and reliable sanitiser level at all times. Contains 650g/kg available Bromine and 280g/kg available chlorine. Effective over a wider pH range than chlorine alone. Less odour and slower dissolving than chlorine tablets. Ideal for indoor spas, and pools with attached spas because of reduced odours.
