Elemental Squared Mineral Cartridge
The replacement for the Sundance Spas’ Sunpurity leaves water clean, clear and soft. An alternative to chlorine when used in combination with MPS (monopersulfate), the Elemental Squared Mineral cartridge fits into the bromine dispenser of the filter bays of 880 and 780 Series hot tubs. It reduces the potential for unpleasant odors and residue lines, and can be used with your hot tub ozone system. Lasts up to four months. Note: The Elemental Squared requires only a small maintenance dose of non-chlorine oxidizer and should not be mixed with bromine and bromides. The Elemental Squared Mineral cartridge is not compatible with biguanides such as SoftSoak or Baqua..
