Why does my hot tub feel slimy?

• <div><p>Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm. </p></div>

Q: What is the lifespan of a swim spa?

• <div><p>Similar to a hot tub, swim spas last anywhere from five to 20 years, depending on quality and your attention to maintenance. The best way to increase the lifespan of your swim spa is to carefully maintain it&mdash;including draining it around every six months to deep clean the parts.</p></div>

Q: Are air baths good for you?

• <div><p>Yes, air baths are good for you. They promote relaxation, improve circulation, and can even hydrate your skin. Since they&rsquo;re gentler than water jets and whirlpools, they are a good choice for a wide range of homes and users, from children to adults. You can maximize the benefits by using them regularly for stress relief and by pairing the bubble effects with calming music, low lighting or chronotherapy, aromatherapy, and other relaxation techniques.</p></div>

Q: Can a crack in a hot tub be repaired?

• <div><p>Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.</p></div>

Follow these general safety tips for spas and hot tubs:

Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.
Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution.
Don’t use the hot tub or your pool during a thunderstorm.
Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes.
