Hot Tub Chemical Alternatives

Hot Tub Sanitizing Options: Alternative Approaches to Keeping Your Spa Clean

Hot tub maintenance is a crucial part of a long-lasting spa experience and safety of anyone taking advantage of its relaxing benefits. The high temperatures a hot tub creates an environment that is suitable for quick bacterial growth, which is why you need to pay particular attention to its care.

Luckily, this isn’t a difficult thing to do, and many filter options, chemicals, and hot tub chemical alternatives, exist to help keep your water clean and your soaking experience safe. Take a look at the following treatment suggestions to help keep your tub running as it should.

The Three C’s

Keep in mind the three C’s for a clean, sanitized spa experience: Circulation, Cleanliness, Chemicals. These three work together to provide safe soaking and a long-lasting, more energy efficient hot tub. The products listed below work with these steps to ensure a clean, healthy, soaking experience.

Circulation

Moving water is critical to allow for proper water filtration. Most spas have a built in circulation timer that runs a few times a day for 15-20 minutes to filter out any impurities that have made their way into the system. If your tub doesn’t have this feature, you can simply turn it on and allow it to run for about an hour once a day or every other day. This is especially important for when you aren’t using your tub very often.

Cleanliness

Wipe down the sides of your tub at least once a week, and do a more thorough drain and wipe down every three to four months, with a vinegar and water solution. Also, rinse and soak your filters regularly, especially if your tub has high usage. Replace as needed.

Chemicals

Measure your water pH, alkalinity, and sanitizer levels using simple chemical test kits. This should be done when fresh water is added, and then at a minimum, once a week to determine what changes you need to make to keep your water clean and safe. Maintenance kits keep your water levels where they need to be:

pH

tester with tablet and powder of chlorine or bromide for mainteance of water quality of jacuzzi or spa

To keep your sanitizer working as it should and to avoid water cloudiness, your water should test in a 7.2 to 7.8 pH range. If low, cloudy water will occur; if too high, the acidity of the water will wear away at your machinery.

Alkalinity

Try to keep your alkalinity range between 80 and 120. Ranges outside this will keep your sanitizer from being effective, and high ranges will result in scale buildup and cloudy water.

Sanitizer

Always follow the directions on your sanitizer (chlorine or bromine) packaging. Check after it has mixed thoroughly for pH and alkalinity levels.

Shocking the Water

pool maintenance equipments and chemicals

Sanitizers aren’t long lasting and are only efficient for a set amount of time, hence why you need to measure your pH and alkalinity on a regular basis. A spa shock is recommended to help remove organic contaminants (think of everything you BRING into the pool with you), kills bacteria, and removes the odors associated with chemicals (which is a waste product of the chemical itself).

This should be done once a week or more if it is used heavily even if you take advantage of the alternatives listed below. If you are choosing alternative options for sensitive skin, you may want to stay out of the water for at least 24 hours after a shock.
