Bromine is easier to use than chlorine and it performs better at the high water temperatures found in hot tubs. Bromine is less of an irritant and smells less than Chlorine. It is easier to use, but can sometimes cause foaming. |
Chlorine is the traditional hot tub chemical sanitizer and probably the cheapest, but it is one of the most toxic and the hardest to use! Chlorine can smell unpleasant and can cause skin irritation to sensitive people, particularly if not used carefully. |
Two plastic canisters, one containing Bromine and the other minerals. The minerals enable the bromine level to be minimised Spa Frog dispensers are built into some hot tubs. Easy to use but can be difficult to control the bromine level. |

Baqua Spas uses the chemical biguanide as a santizer and is very popular in the USA. Easy to use but be very careful about mixing with components from any other hot tub water care system. |
Active Oxygen is a gentle, odourless alternative to the traditional method of disinfecting your hot tub water with chlorine or bromine. Not as toxic or irritant as chlorine . Requires tablets to be added with each use. |
