We have selected the following ‘QualAqua Quality Approved’ spa chlorine granules as suitable and for all hot tubs and spas.
We recommend that you use chlorine granules in a tub (rather than chlorine tablets) because slow dissolving chlorine will cause fumes to be trapped in your spa while the cover is in place. This in turn can cause bleaching of the spas surface above the waterline, and can also cause vinyl cover materials to rot! Chlorine granules are also cheaper. If you must use chlorine tablets in your spa, please view the chlorine tablets section.
The following spa chlorine granules are fast dissolving high quality grade 1 chlorine products from reputable brands.
