Can I raise the alkalinity in my hot tub?

• <div><p>Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.</p></div>

• <div><p>How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months.

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.

"I purchased a Heavenly Heat Sauna a few weeks ago . What I liked is you don?t smell any glues . I also liked its easy ( two man ) assembly. What I don?t like , in order to avoid using glues, they use pins or very thin nails. Some pins were missing and some were not beneath the surface. For the rough edges you?re provided with a small piece of sandpaper . Bot at a cost of over 5k you don?t expect to do sanding. My biggest complaint is that it takes almost an hour to get the sauna to 150 degrees. Definitely not worth the price. "

Pool and Spa Servicing questions, answered by experts

How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it’s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner’s manual.

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.

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’t add chlorine to your hot tub water more than once per day.
