Importance of Hot Tub Maintenance

Even if you keep your tub well covered, it is going to get some dirt and debris in it from the surrounding environment. On its own this isn’t usually that big of a deal and may not even be very noticeable due to the use of a filter- but once you begin using the tub as you should, you are going to see a big difference.

Every time you set foot in the tub every bit of dirt, dead skin, body oil, and perspiration is getting washed off in the water. If you use a lotion, the residue will be left behind; if you use hair products, they now have been added to the water; and whatever you feet came in contact with before stepping in the water is also in the tub with you- or is it?

This is a common cause for dirty water and sounds gross, but in reality isn’t as bad as it seems because the chemicals you use are actively attacking any bacterias and other yuckies you may have just introduced. They break these down quickly and allow anything left behind to efficiently filter to keep you soaking in clean water- rather than the disgusting human soup I just described.

Circulation, cleanliness, and a working chemical system are the three C’s you need to keep in mind for a clean, sanitized soaking experience. They work together to help keep your water safe and so choosing the best hot tub products to use is important. Using these as they should will keep you from having any major issues, or wondering how to deal with hot tub foam and other minor inconveniences.

Circulation

Spas need to run regularly to circulate water and stir up any foreign matters or dirt suspended in the water for filtration. Many spas have an automatic cycle to run a few times a day even when not is use, but if your spa does not have this feature you will need to turn it on to run at least once for 40 minutes to an hour.

A good filtration system is a must, and to make it even more effective, you can choose various chemicals to help break down dirt and debris even more so it can run more efficiently.

Cleanliness

The humid, moist environment created by a tub is the perfect breeding ground for bacteria and mold. Wiping down the cover (top and bottom), sides of the tub, and edges of the tub at least once a week is crucial to helping keep the environment clean. Every few months you should drain your tub and wipe it down with a bleach solution and/or vinegar based cleaner as well.

Chemicals

Test your water regularly for pH, alkalinity, and sanitizer levels with test strips. Always do it when you add fresh water,and, at a minimum once a week so you can adjust your chemical additions as needed. Although the responsibility of this may seem daunting, it is easily done using simple test kits that can test your levels, and also supply all you need for maintenance. Follow the directions of the brands you buy to determine how much chlorine is needed (or bromine) to avoid waste.

Water Shocking

Chemicals are also a part of the water shocking process. This should be done at least once a week, or more if the spa is used heavily, to remove organic contaminants, keep your filter working more efficiently, remove bacteria and odors, and provide the proper chemical levels you need. The best hot tub sanitizers include bromine and chlorine options, and work with various other products to provide variations in your personal preferences.

If you have sensitivities, you can easily research the best hot tub chemicals for sensitive skin to discover what possible alternative are available to ensure you have a clean, safe, yet comfortable soaking option treatment.
