How Often Should You Change Hot Tub Water?

Changing the hot tub water is necessary regularly, even when using chemicals to disinfect the tub. Developing this habit ensures you keep your hot tub healthy and promotes good health for yourself. You can identify when to change the water by paying close attention to your hot tub and observing specific characteristics.

You need to change the water every three to four months, and here is why. As you add chlorine to the water, it dissolves gradually every time and eventually does not dissolve in your tub. Your tub water can only hold as much chemical concentration before becoming supersaturated. Practical symptoms of supersaturated hot tub water include cloudy elements and a foul smell. Other reasons why you need to change your hot tub water are explained in this article.

Why Change Your Hot Tub Water Frequently?

Cloudy Water

It would be best to consider changing the water every three months to avoid cloudy water in your tub. We can all agree that a cloudy hot tub is not that inviting and might expose you to bacteria and other harmful elements. Some individuals prefer spa shock to clear the tub temporarily, but the best solution is to change the water.

Tiny Bubbles

Tiny bubbles are standard in bathtubs, not hot tubs. You may need to replace the tub water if you see foam in your tub to clear it. A foam remover can provide a temporary solution and allow you to extend the water change. If it does not work, change your hot tub water to eliminate what is causing the bubble build-up.

Dirty Water Smell

You risk exposing your hot tub to a bad smell by refusing to change the hot tub water frequently. No foul smell should come from the tub or water, even after introducing chemicals. The primary causes of the bad odor include mildew, bacteria, or biofilm in the structure's plumbing. Changing the hot tub water is the only way to eliminate the foul smell.

What Will Happen If You Fail to Change Your Hot Tub Water

Supersaturation

Water limits how many substances it can accommodate before becoming supersaturated. When water becomes supersaturated, it can no longer dissolve other foreign elements. You may start observing these mineral and chemical deposits as scaling on your hot tub fixtures, in the tub, or filter. Scaling builds up, eventually damages the tub's surface, breaks its components, and will cost you for repairs.

Total Dissolved Solids

Calcium is not the only build-up in your hot tub. You also leave behind contaminants like sweat, makeup, lotion, and other bodily fluids in your hot tub water. They are total dissolved solids and can cause future tub complications. The water becomes murky, feels gritty, and develops a foul smell once concentrated with excess TDS. The more you ignore changing your hot tub water, the less clean water there'll be.

Changing your hot tub water is necessary every three to four months. It would help if you considered investing in an efficient cleaning routine to improve your health and extend the tub's longevity.
