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: How do I keep my hot tub clean naturally?

• <div><p>If you want to have a chemical-free spa, or if you are wondering how to keep your hot tub clean naturally, there are several options. Some individuals choose to run their hot tub without treatment at all and simply clean it more often (although you risk bacteria, fungi, and algae growth if you take this route); others use natural products like vinegar or Borax. Ozone, ultraviolet light, and electrolysis systems are also eco-friendly ways to have a clean hot tub without chemicals. Saltwater hot tubs are popular with people who are sensitive to chlorine, bromine, and other traditional hot tub chemicals.</p></div>

Q: How many years does an outdoor hot tub last?

• <div><p>Most outdoor hot tubs last between five and 20 years, excluding inflatable tubs, which last five to seven years. High-quality, maintained tubs can last decades, while low-quality, poorly maintained tubs may not hit five years. A good warranty, professional installation, quality materials, and proper maintenance will help a tub last longer. </p></div>

Q: How often should you put chlorine in your hot tub?

• <div><p>You should put chlorine in your hot tub on a regular basis. To keep bacteria away, keep the chlorine level in your hot tub at between 3-5 mg/l, which may mean you need to add chlorine daily or at least every two to three days. Don&rsquo;t add chlorine to your hot tub water more than once per day.</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>

Heavenly Heat Infrared Saunas are made for the chemically sensitive. That means that our infrared saunas create an ideal, safe, and effective detoxification environment for anyone seeking to eliminate toxic substances from their body.

"Terrible! Wish I had gone with another company. Here is the issue with Heavenly Heat. If your sauna arrives damaged or and issue arrives -- they have zero technical support. Your repairs will be done by any "joe" that heavenly heat finds to do the repair in your area. They will have no experience with Sauna's and are given no instructions regarding the chemical free aspect of these sauna's. The worst part is the buyer, me, was treated as if I was the problem for wanting my sauna repaired correctly. I would have refused the delivery had I realized I was receiving a damaged sauna and would have to spend hours and days trying to get this resolved. The owner, Bob Morgan, is extremely responsive before he has your money but after, is a different story. When inquiring about the sauna he would respond generally within 10 minutes. After you purchase, and particularly if you have a problem with it, you are treated as if you're a nuisance. My sister bought a competitors sauna around the same time and the service she received from knowledgable representatives was a world of difference from my experience. My other issue was that there were shipping delays and Bob would never communicate them. I would have to pursue him to get information. I think they make a decent sauna but I would not recommend for reasons stated above."
