You don’t need to be some kind of chemistry whiz to master clean and clear water in your hot tub. However, understanding certain elements of water chemistry and their interactions may make it easier for you to make your spa sparkle. The secret to maintaining a sanitized spa is all in the upkeep, so follow our simple do’s and don’ts for an inviting cloud-free, bacteria-free backyard oasis.
Don’t Underestimate Total Alkalinity
Your spa’s total alkalinity (TA) determines the pH levels of the water. Low TA results in low pH levels, while high TA levels increase the pH reading. TA is an extremely important aspect of your hot tub maintenance, so test it before moving on to the pH tests. For best results, check on the TA every three to four weeks.
Do Clean the Filter
Your hot tub filter is responsible for trapping all the oils and hair from your bathers. If you ignore your filter, it may clog up and stop working, in which case you’ll have a grubby tub and murky water on your hands. To avoid problems with your filter, clean it every 4 to 6 weeks. Ask your hot tub provider or consult your owner’s manual for tips on properly removing the cartridge and rinsing it.
Don’t Forget about Calcium Hardness
Low calcium levels in your spa can cause equipment corrosion while high levels may lead to water clarity problems. Measure your tub’s calcium hardness with test strips or kits to determine your course of action. For low levels, you may need to invest in a calcium booster. Meanwhile, high levels may require you water softener treatments.
Do Decide on a Sanitizer
Sanitizing your tub will keep it clean, clear, and bacteria free. Not only do sanitizers disinfect your spa, but they also fight against odors. Bromine and chlorine are two of the most popular sanitizers, so speak with a hot tub expert or do you research to determine which sanitizer is best for you and your spa.
