Q: Why does my portable spa use bromine but pool uses chlorine as the sanitizer?
A: Chlorine is the industry standard for sanitizing a pool. However, since portable spas are typically kept at a much higher temperature than pools, bromine is the preferred sanitizer for spas. Bromine is more effective than chlorine in hot water conditions.
Q: How often should the water in my portable spa be changed?
A: Generally speaking, the water should be changed every three to six months, depending on usage.
Q: How often should I clean my filter cartridge?
A: Whenever the spa is drained, you should also remove and clean the filter cartridge. Keep in mind, some portable spas have multiple cartridges so be sure to remove and clean them all.
Q: Should my portable spa be winterized?
A: If you intend to drain your spa and not use it over the winter, then it should absolutely be winterized in the fall. This will ensure all the water is removed from the plumbing and equipment. Draining the spa is not sufficient, as some water can remain in the plumbing and equipment, freeze and cause costly damage.
Q: How often should I test the chemicals in my spa?
A: Water should be tested minimally once per week. Specifically, it’s the bromine (or chlorine), pH and alkalinity that should be tested.
Q: What is the ideal level at which I should keep the bromine (or chlorine), pH and alkalinity?
A: It’s best to strive for a bromine or chlorine level of 1-3ppm, a pH level of 7.4-7.6 and an alkalinity level of 80-120ppm. Chances are you won’t be able to get all three tests to balance perfectly. To get your spa water balanced as best as possible, focus first on getting your alkalinity level in the ideal range, then your pH level and finally your bromine (or chlorine) level.
Q: What chemicals should I add to adjust my chemistry levels?
A: To adjust the alkalinity level, use sodium bi-carbonate to raise the level or dry acid to lower the level. To raise the pH level, use soda ash or sodium carbonate. To lower a pH level, use dry acid. To adjust bromine levels, add non-chlorine chock. If your spa uses chlorine as its sanitizer (instead of bromine), add chlorine shock to raise the chlorine level. Always be sure to read and follow the chemical manufacturer’s instructions.
