Calcium hydrochloride (or HTH as commonly known)
Is traditional granular chlorine that requires regular daily addition to the pool. It is an unstabilised chlorine, which means that it is not protected against sunlight and has a higher contribution to TDS. It does require regular maintenance of the pH as the high pH of this chlorine will drive the pool’s pH up over time.
Chlorine feeder
Floater is an easy-to-use monthly disposable floating chlorine. It is stabilised chlorine, which means that it is protected against sunlight and has a low contribution to TDS. It nevertheless does require regular maintenance of the pH as the low pH of this chlorine will drive the pH of the pool down over time.
Chlorine pills 8’s
Is suitable for use with floating baskets or semi automatic feeder installations. It is stabilised chlorine, meaning that it is protected against sunlight, and has a low contribution to TDS. Regular maintenance of the pH is still required, as the low pH of this chlorine will drive the pool’s pH down over time.
Ultra-Chlor
Is a new-age granular chlorine which requires regular addition (every second day) to the pool. It is stabilised chlorine, which means that it is protected against sunlight, and makes a very low contribution to TDS. The regular maintenance of pH is not required, as the near-neutral pH of this chlorine will have only a limited effect on the pool’s pH over time.
Salt water chlorinators
Where fitted (and correctly sized for the pool), will provide the regular supply of sanitiser, provided that the required salt levels are maintained. These pools should not need the addition of any other sanitiser on a regular basis. Stabiliser is, however, very important in these pools. Refer to your chlorinator manufacturer’s instruction booklet for further details.
