Hot Tub: Care and Maintenance

People often get hot tubs to help find relaxation, happiness, and health that they can share with their friends and family.  Improve your day-to-day well-being by enjoying the nurturing massage and warm water, which improve the way you look and feel. 

Health benefits of hot tubs. The hot water and temperature in a hot tub can help your body recover from a hard workout, reduce stress on the heart and brain, increase your blood volume, improve blood flow, stimulate circulation, lower the level of stress hormones, decrease blood pressure, raise your heart rate and blood oxygenation, and improve your immune system.

If you’re looking to purchase a hot tub I recommend getting one with an ozonator built into it.  The ozonator is the sanitizer, it literally makes drinking water although I don’t recommend sipping what you're sitting in.  Although the manufacturer does recommend using a sanitizer, I have a client that I clean the swimming pool for and he has a hot tub with an ozonator that all I’ve done in 10 years is keep the PH balanced and clean the filter and the water is still sparkling clean.  

Old Versus New

If you already have a hot tub at your place I can’t stress enough to take good care of it.  As soon as you get in, the ph starts to change, usually getting acidic.  Acidic water is not only harsh on your skin and eyes but wreaks havoc on the heating element.  

Now let’s talk about stewing in your body fluids.  Yes it sounds gross but I want you to take this seriously.  I also don’t want you to fill that tub up with chlorine and choke you out with the fumes.  In fact, we don’t use chlorine in hot water, we use Bromine.  Bromine is another type of sanitizer that’s made for hot water and most commonly comes in one inch tablets.  You can get a little tab floater to leave inside the tub.  

The best way to treat your hot tub is to add some kind of mineral algaecide to the skimmer.  They usually come in a plastic stick or ball.  This will help reduce the amount of Bromine that you will need to use.  In fact, use about half of what your test strips say to use.  

The next thing to have in your arsenal is some good non-chlorine shock.  If you have a heavy bather load or the water gets a little cloudy just through the recommended amount in the tub.  It’s a good idea to just toss a little in after each time you get out.  The non-chlorine shock quickly dissolves the body fluid and helps the filtration.  

Speaking of filtration, keep that filter clean.  Somewhere in the spa you have a small cartridge filter that needs to be taken out and hosed off once in a while.  This depends on how often the hot tub is used and how many people are using it.  

Draining your hot tub.  You will need to drain it once in a while, again, depending on how often it is used and how many people are using it.  Plan on draining it quarterly.  To help you make this decision let me just remind you that it is a big bathtub that everyone is using.  To make it easy on you I often tell my customers who have a swimming pool to just drain it into the pool when it needs some water.  You can also turn it off and leave the lid off until it cools down and the chemicals dissipate and water your trees with it this way you don’t feel like you're wasting water, and always, take time to enjoy!

Warnings and things to watch out for.  Since the water in a hot tub is higher than your normal internal temperature, staying in a hot tub too long can cause you to overheat and experience symptoms like light-headedness, dizziness, or nausea.  These symptoms are your body’s way of telling you that it is time to get out of the hot tub and cool down.
