Hot tub maintenance is perceived as a demanding task but it's necessary if you want to use your spa safely.There are over 5.8 million hot tubs in American homes, which is not surprising given that a high-quality hot tub can last 20 years or longer.
But how can you make your hot tub last that long? How to avoid it and how to make the most out of your bathing experience?
In this article, we put up a beginner's guide to hot tub maintenance. Following these simple tips, you will find out how to keep your water clean and clear.
You need to get acquainted with these terms if you want to become a hot tub maintenance pro:
Circulation in your hot tub helps prevent contamination by bypassing the hot tub filter.
You can install an automatic flow control in your hot tub to make sure that water flows once or twice daily. This cycle circulates the fluid for around 10-15 minutes, ensuring that the filter absorbs all moisture.
Turn off your spa for 20 to 20 minutes twice a day for fresh water.
A clean hot tub filter is priceless, as it guards against murky water, foul odors, bacteria, and the dreaded algae bloom.
Keeping the spa filter clean is also essential for hot tub maintenance if you want to avoid cloudy water. Hot tub filters need cleaning, depending on how frequently you use them.
A hot tub filter can become clogged and rendered ineffective with body lotion, hair gel, or other body-care products in the water. Regardless of how recently your spa filter has been serviced and cleaned, these products can still result in murky water. Keeping hot tub filters clean is essential.
Using a hot tub filter cleaner and degreaser regularly can extend your spa filter's life and save money. If you don't have a product like this on hand, you can clean the filter with dishwashing detergent (the kind you would use for hand-washing dishes, not automatic dishwasher detergent).
Keep your hot tub water clear and clean by cleaning your spa filters regularly. We recommend that filters be changed every 6–12 months and cleaned every 2–4 weeks (depending on usage). Using a garden hose, rinse the filters out of the tub and remove them from the tub. Soak them in a filter-cleaning solution overnight for a more thorough cleaning process. Use the product's label as a guide.
Regular hot tubs need regular chemical treatments to keep the water pathogen free.
Here is a list of the main hot tub products and their purpose.
Some people use other products that are not commonly used for hot tub maintenance, this is why they are called unconventional:
The most important part of tub maintenance is chemistry balance. If you overlook this aspect, all others are useless. Here is what you should consider:
PH is a measure of the acidity or basicity of your water. The pH scale runs from 0 to 14, with 7 being neutral. Anything below 7 is considered acidic, and anything above 7 is considered basic.
Maintaining the proper pH level in your hot tub is essential to preventing skin irritation, cloudy water, and calcium buildup.
The ideal pH level for hot tubs is between 7.4 and 7.6.
You can balance the pH in your hot tub as follows:
Muriatic acid can be used to modify the pH of your solution. It can cause severe damage to the hot tub surface if used in excess. The pH of your water can be maintained by adding spa enzymes, which break down organic materials in the water.
Total alkalinity is a measure of the ability of your water to resist changes in pH, as follows:
The ideal alkalinity level for hot tubs is between 80 and 120 ppm.
Test the total alkalinity of the water and check the pH. Make any necessary adjustments. Retest both to ensure they're within acceptable limits.
You can balance total alkalinity as follows:
High pH or alkalinity is most likely to blame for a cloudy tub. Adding a flocculent, which clumps the particles together, will allow them to be filtered out if the water is only somewhat hazy. Drain the tub and start over if the water is unclean.
Measure your water hardness using a test strip and follow these instructions in case you experience an imbalance:
The most straightforward technique to keep your hot tub's calcium hardness under control is to utilize soft water. Scales build in your hot tub in case of too much calcium hardness. To protect yourself from these scales, apply a spa defense solution.
If your spa's calcium hardness is insufficient, the water will begin to draw minerals from other sources, such as the hot tub shell, resulting in discoloration and etching.
Here is a list of the most common types of sanitizer for hot tubs:
It's impossible to say how much sanitizer is needed because every hot tub owner uses their hot tub differently. If your water doesn't require any adjustments, we recommend testing and monitoring the amount of disinfectant and PH more frequently and making adjustments as needed.
Shock treatments break down sanitizer residue and other contaminants, which would otherwise provide food for bacteria to thrive on. You can use chlorine shock treatments or non-chlorine shock treatments on your sanitizer.
Balance the spa water once a week, and remember to perform a shock treatment after a rainstorm, water change, or if the water appears cloudy.
Your tub may need to be descaled frequently if your water is particularly hard. Mineral build-up can result in foamy water and make it difficult for chemicals to work properly. Use a commercial descaling product or a vinegar-water solution (1 part vinegar to 3 parts water) to remove mineral deposits. The vinegar-water solution or the product label instructions should be rigorously followed.
Foamy water is often caused by using too much soap when bathing or by using harsh soaps and shampoos that contain chemicals that can interact with the hot tub's chemicals, causing foam.
Body oils, cosmetics, lotions, and other goods are frequently implicated. You can avoid frothy water by following a water maintenance routine and showering before entering a hot tub.
Keeping the defoamer on hand, on the other hand, is an excellent idea, especially if you're hosting a party or have new hot tub visitors.
To eliminate foamy water, first, check the pH and alkalinity levels. If they are not balanced, make the necessary adjustments. If the problem persists, try adding a defoamer to the tub. Follow the instructions on the product label. To altogether remove the foam, you may need to add the defoamer more than once.
Hot tub foam can be caused by a number of things, including:
To get rid of hot tub foam, you'll need to adjust the pH and alkalinity levels in the water. You may also need to add a clarifier to remove small particles that are causing the foam. Foam can also be caused by using too much hot tub product, so follow the manufacturer's directions.
Testing spa water is essential for maintaining safe water. A test strip lets you know quickly & precisely the levels of the:
The resulting chemical adjustments can be made as needed. All owners of hot tub facilities are responsible for monitoring and sanitizing their baths every day, as the water requires regular cleansing. If using an experiment strip, a person needs to follow the directions on the bottle for better reading carefully.
Test the contents of your water weekly using test strips. Make any necessary adjustments to your fluid composition. It would help if you kept a routine for hot tubs to boost the spa maintenance program. Your hot tub skills will increase as you learn more sophisticated jobs, reducing unpleasant surprises.
Besides what we have presented above, there are other techniques to keep balanced water chemistry for hot tubs:
Follow these steps to provide proper cleaning for your hot tub:
Hot tub lines can accumulate build-up, resulting in hazy and odorous hot tub water. Reduced jet pressure can potentially be a result of the accumulation.
Before draining the hot tub, clean the pipes with a line flush or plumbing cleaning. Line flushing directions differ by product, so read them carefully.
While you're at it, give the hot tub cover a quick once-over with a 10% bleach-to-water solution to keep mildew at bay. A weekly clean is essential for hot tub care.
Over time, minerals, chemicals, and other soluble compounds absorb your spa water, raising Total Dissolved Solids (TDS). The same principle applies to adding sugar to a cup of tea until it no longer dissolves. TDS reduces the efficiency of spa chemicals, resulting in flat, hot tub water that is more difficult to maintain.
With the preceding in mind, BISHTA recommends changing the water in a small (2-3 person) domestic hot tub every 3-4 months and more frequently (every 4-6 weeks) in more oversized hot tubs or those in constant use.
While you don't have to drain and refill your spa after every use, every three to four months helps remove built-up dirt, oils, soaps, and other potential contaminants that can cause cloudy water. It's good to drain and refill your tub when you can no longer see the bottom drain.
Hot tub surfaces are usually cleaned with substances and sponges that don't affect the material they are made of. We don't recommend using harsh chemicals for this step because the residue can affect the hot tub water balance. Natural products, such as sodium bicarbonate, will suffice if the spa is not scaled.
Periodically cleaning your spa cover reduces your workload. Follow these steps for a correct cleaning process:
To avoid adding dirt and debris to your hot tub, use a grade hose with a backwash filter attached when changing the water. Drain the old water into a large container or outdoors.
Fill the tub halfway with clean water and test the pH, alkalinity, and calcium levels. As needed, adjust the levels. After the new water has been appropriately balanced, turn on the built-in heater and add your preferred chemicals to the tub.

Here are some tips on how to add chemicals to the hot tub water:
Here is a list of pro tips for hot tub maintenance:
Simplicity and consistency are the key elements of the regular maintenance of hot tubs. Work is less stressful when it is broken up into small pieces that are easy to handle.
This strategy, known as chunking, is employed by educational and commercial leaders worldwide to increase productivity.
Every 3 to 4 months:
Hot tub maintenance is not complicated if you take into account three essential elements: circulation, filtering, and water chemistry balance. If you understand how to provide balance to your hot tub, you can provide safety for the users and prolong the lifespan of your hot tub. This can be achieved by keeping a strict schedule, especially if you use your spa often.
