Pool Maintenance

When owning a personal home pool, or indeed a hot tub, there are several elements of maintenance that need to be regularly carried out to ensure that the water stays safe and clean, the swimmers remain healthy, and the structure of the pool or tub doesn’t perish or suffer damage. 


Whilst it’s fair to say that a filter is the heart of the swimming pool, it could also be seen as the liver, helping to (as its name suggests) filter foreign objects and contaminants from the swimming pool to ensure maximum cleanliness and functionality. 

As such it plays a vital role in the longevity and effectiveness of your pool, which means maintenance and upkeep is incredibly important. 

Some filters can be changed, and others need regular cleaning and maintenance.

Check to see what care your filter needs, and make it part of your cleaning routine. 

Skimmers And Returns

These are important parts of the overall filtration system. Lining the circumference of the pool, skimmers and returns are responsible for drawing and circulating the water to the filter and back into the pool. 

Keeping these clean and clear of obstructions is paramount to maintaining a healthy swimming pool.


Pool hygiene is a big thing when it comes to both home systems and commercial ones. 

Regular drainings must be undertaken, during which the interior of the empty pool or tub should be scrubbed (to ensure no grime or mildew has formed), and the water should be replaced. 

True with both pools and hot tubs, it is important to also regularly maintain, clean, and (in the case of tubs) change the filter where necessary. 

This ensures that no potentially harmful grime, algae, corrosion, or other foreign substances can enter the pool, taint the water quality, or indeed harm the swimmers.


Chemical care is also required to maintain the cleanliness of the water, and to protect the swimmers from germs. 

Grime can build up over repeated use, as the oils and lotions (both natural and unnatural) on our skin filter into the water and make it greasy. 

To ensure perfect pool health, it is important to keep pH levels balanced, chlorine levels at the right level, and make sure that the alkalinity and acidity levels of the water are within safe parameters. 

Chlorine is effective at killing germs and harmful bacteria, and can be commonly found in all hardware stores, or wherever they stock pool or hot tub supplies. 

The same can be said for pH neutralizers, alkalinity tablets, and other useful accessories, such as defoamers to increase water cleanliness. 

Additional Accessories

Other useful accessories include litmus test strips for pH testing.

These are mainly for hot tubs, but can also be used for swimming pool maintenance, and can be found in most hardware stores, or wherever you can purchase pool/hot tub supplies. 

Similarly, new interchangeable filters can be purchased for hot tubs, allowing for improved water cleanliness and better tub hygiene. 

Three Important Things To Remember

Whilst there are many things that are important to the long term health of your swimming pool, there are three main aspects that are more important than the rest. 

Good Water Circulation

Bad pool circulation can lead to moss, algae, and bacteria, potentially harming the health of the swimmers.

As such it is important to keep things like skimmers, returns, and filters working correctly. 

If you don’t want to run your filter all the time, it is recommended that you have it on for at least 12 hours to ensure good filtration and continued cleanliness. 

This ensures that the water gets circulated a good few times and will help to reduce the need for drainage and refilling. 

A Good Cleaning Schedule

As we have discussed, cleaning is perhaps the most important aspect of owning a pool.

That is unless you want the constant hassle of draining, refilling, and scrubbing the interior. 

There are several options available, be it chemicals or automatic pool cleaners (see also ‘Best Dolphin Pool Cleaners: Reviews & Buying Guide‘), which can make the task less time consuming and exhausting. 

One strange yet handy tip is to throw tennis balls into the skimmer basket or into the pool itself to absorb greasy body oils and grimes. 

Good Water Chemistry

As this guide will show, a good tool to own is a water monitor or a testing kit.

These are vital to ensuring the continued health of your swimming pool, and can make the whole process of chemical testing much quicker than if you were using good old fashioned litmus strips. 

Once you have a solid reading of your chlorine, pH, alkalinity, and acidity, you can then add chemicals accordingly until you achieve chemical neutrality (and a chemically safe pool). 

The best way to achieve all of this is to establish a firm working schedule and stick to it. 

Chemicals will need to be monitored several times a week (sometimes more after adverse weather conditions or heavy use), whilst cleaning will need to be done every few months to ensure continued cleanliness. 

As far as filtration goes, this can checked and maintained every few months too, ensuring there is no major detritus or obstructions in the skimmers and returns, and cleaning (or exchanging in some cases) the filters to make sure they are not stuck up grime, algae, dirt, or mildew. 

This is a much easier method, and the routine will make it become second nature before long, making it less work/effort. 

Smart Pool Monitors

Suited for both commercial settings, such as larger public pools or spas, but also for home use, smart pool monitoring systems are useful and effective tools for keeping active, accurate track of pool hygiene. 

What Are They?

Simple to use, and effective for ongoing maintenance, smart pool monitors keep accurate records of chemical levels, pH levels, up to date water analyses, and overall cleanliness. 

They are often very user friendly, usually offering smartphone pairing for an accessible, user friendly interface, and are a great way of keeping up to date with the condition of your pool without the need for manual water tests or needless experimentation with various available pool chemicals. 

With a smart monitor, you are able to tell straight away if the water quality is up to condition, something that can prove both time saving, and money conscious, as there can be less waste over time. 

What Do They Offer?

Putting it simply, they offer the ability to easily visualize the overall chemical health of your swimming pool in one handy, easy to read format, allowing you to make the best decisions going forward, without excess time or energy. 

Only sending you notifications when there is a chemical imbalance detected, you aren’t hassled by the technology, letting it work for you and your needs, instead of the other way around. 

You also have access to historical water analysis data, meaning that you have an up to date and accurate view of your water quality, as well as the regime of chemicals you have been sticking to over certain periods of time. 

This can be handy after long periods of absence from home, where you might have forgotten the last time chemicals were added. 

It can also help you to more quickly ascertain faults or problems with your pool, as signs of imbalances after a recent refill or chemical dump could be early warning signs of faults with pipes, internal plumbing, or even mold or algae within the tiles. 

For less technically skilled customers, the devices generally offer easy to follow steps about the required actions that need taking, meaning you have substantial help when it comes to ensuring the continued health of your pool. 

What To Consider Before Buying


The ratio of performance to cost is one that is important to consider when shopping for equipment. 

It often comes down to finding the best pairing of the two, seeing what can offer you the most bang for your buck and making a choice. 

The most expensive model on the market doesn’t necessarily mean you are buying the best, and often you can be paying higher costs for a name or brand that is popular. 

Nowadays, with the growing accessibility and popularity of home pool equipment and accessories, it is easier than ever to pick up bargains or hidden gems if you shop around enough. 


However, when it comes to buying equipment for swimming pools, or indeed any other item that holds a degree of importance to health and cleanliness, it is important to opt for established, trustworthy brands who have proven records for delivering quality

This not only ensures a greater chance of effectiveness, but also helps protect you in case of faults or issues, as sanctioned companies generally have more direct and reliable communication channels for returns, exchanges, and refunds. 

They will generally have better customer service, as well as the ability to offer tech support should any minor hiccups occur during the installation process. 


Of course, another important thing to consider are the specifications of the items you are looking to buy. 

This probably goes without saying, but before parting with your money, it is important to ensure that the product both does what it promises, and meets the specific needs you have for your home system. 

These specifications factor in with the pricing, and it is often the case that you have to compare the function with the cost to see what item ticks the most boxes. 


Finally, you want something that is both attractive and user friendly.

Attractiveness might seem unimportant, but most people’s home pools are statement pieces in their gardens or homes, and ugly equipment can bring down the appeal of such pieces. 

Also, if you are spending money on a product, you ultimately want it to look nice with your existing setup. 

User friendliness is also paramount, as you don’t want to be blinded by science every time you want to check your pool’s health. 

You want ease of use for added efficacy, as this will make the whole process much simpler and worth the investment.

RCYAGO Digital PH Monitoring System

This 5 in 1 water quality tester is a simple and effective way to monitor pH levels, tds levels (total dissolved solids), EC levels (electrical conductivity), salinity levels (the level of salt in water), and water temperature in your pool or home spa. 

When measuring salinity in water, this is categorized as fresh water (less than 1000ppm), brackish water (river/groundwater at 1000-10,000ppm), saline water (10,000-35,000ppm), and hypersaline (greater than 35,000ppm). 

Similarly Tds, or total dissolved solids, is used to measure the total content of organic, and inorganic solids present in liquid. 

Electrical conductivity is measured in the electrical charge of the ions within the tested water, and can be used to measure the capability of water to pass electrical flow. 

Conductive ions are created as a result of surplus chlorides, alkalis, carbonate, and sulfide compounds, and can be dangerous as far as human beings and swimming are concerned. 

With a high accuracy algorithm chip and responsive electrode, the product ensures accurate and fast response, and the simplicity of use means it is perfect for all skill levels. 

With an automatic power off function (to preserve battery), and a large screen display, the tester has a backlit screen that makes it simple to see measurements no matter the light.
