Most people hate swimming in dirty pools. Furthermore, most people do not know that dirt can damage the liner of pools, pumps, and other essential components, costing people a lot of money in hefty repairs. Therefore, pool cleaning should form part of your weekly maintenance routines if you want to extend your pool’s life. Use the best pool cleaners, as they are effective and come in many styles for different pool types. Before ordering one, you should check your water balance, as it is an important aspect.

What is Water Balance?

Water balance denotes the alkalinity of pool water [also known as total alkalinity (TA)]. TA influences pH balance and the ‘potential of hydrogen’ of swimming pool water. Generally, with a high TA, your pool water with have a higher pH balance, while a low TA will result in low pH pool water.

Why are the pH and TA levels of a pool important? Generally, whenever a pool has a high pH, germs, and bacteria thrive, predisposing users to infections. However, whenever the pH is low, you have an increased risk of irritation to the skin and eyes whenever you are swimming. Low pH also corrodes and ultimately destroys pool parts such as liners and pumps, to name a few.

To maintain optimal pH and alkalinity levels, check your water’s condition frequently using a pH test kit. The standard alkaline level should be 100 parts per million (ppm), while pH should range between 7.4 and 7.6. A value between 0 and 7 denotes low pH, and readings between 8 and 14 high pH.

Low pH water dissolves chlorine quickly, while high pH inactivates chlorine. Chlorine is a critical chemical that kills germs and bacteria in swimming pools.

How to Use a Pool Test Kit

Other aspects of water balance that you should keep in mind include using a stabilizer and calcium hardness. In standard pools, calcium hardness of 300 ppm, range 200 to 400, is suitable. By conducting a calcium hardness test, you will know when pool water needs additional calcium or not to maintain the recommended level of hardness.

Too much calcium in water makes pools to look cloudy, which is uninviting. Moreover, too much calcium can also stain and ultimately damage your pool’s liner, while a low calcium level tends to erode pool plaster.

To prevent chlorine from breaking down faster under the sun, consider using a stabilizer. The device “insulates” chlorine, protecting it from degrading fast.

However, whether you are using a stabilizer or not, do not forget to check your pool’s pH balance and TA often. Maintaining the correct level will keep water clean and soothing and protect pool parts from accelerated damage.

If you have maintained optimal water balance, you should clean dirt and debris from your pool too. This is where automatic pool cleaners are handy. They are three types: pressure side, robotic, and suction-side cleaners.

Suction-Side Pool Cleaners

Suction-side cleaners are equally inexpensive yet effective, making them a top choice for homes. They work with existing pool pump and filtration systems.

Suction-side cleaners are also easy to operate as most models have one moving part. They draw their cleaning power (vacuuming) from pool pumps, which such debris and dirt into your pool’s filtration system for disposal.

Since suction side cleaners require a pool pump with a functional poop pump to work, you might not benefit from one if you do not have a pool pump.

However, they are among the most beneficial in homes as they are affordable. Systems are power efficient as they run off existing pool pumps, while their eco-friendly designs are easy to install, and do not require chemicals to clean.

Pressure-Side Pool Cleaners

Pressure-side cleaners are middle range pool accessories that are slightly expensive than suction-side cleaners but offer many additional benefits.

Is it Necessary to Get an Automatic Pool Cleaner?

People use different techniques to keep their pools clean, including manually operated pool cleaners. The only issue with manually cleaning a pool is the amount of effort and time required to do well.
