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: Should I keep my hot tub running all the time?

• <div><p>Yes, hot tubs are meant to be kept on permanently. It takes more energy to ramp up a hot tub when you turn it on, so leaving it on all the time is more efficient for your hot tub. You can turn the temperature down if you know you won&rsquo;t be using it for an extended period of time to save on energy costs.</p></div>

Q: Can I drain my hot tub into the grass?

• <div><p>Yes, but only if it is a freshwater tub (not saltwater) and if you make sure the chlorine and bromine levels are below 1 ppm.</p></div>

Q: Is green hot tub water safe?

• <div><p>Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including <i>Pseudomonas aeruginosa</i>, bacteria that can cause <a href="https://www.angi.com/articles/preventing-hot-tub-health-hazards.htm">hot tub rash</a>, or <i>Legionella</i> bacteria, which can cause respiratory illness.</p></div>

Q: What temp should I leave my hot tub on when not in use?

• <div><p>The general rule of thumb is to lower it by about five degrees when you know you&rsquo;re not using your hot tub for an extended period of time. With only a slight decrease in temperature, it will be easier to increase it to a desirable level when you&rsquo;re ready to get back in the water instead of starting from scratch.</p></div>

"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."
