Water Options for Your Fibreglass Pool

Whether you are upgrading your pool features or are a first-time pool owner, choosing a pool system is an important investment decision you make in your life. With multiple water systems available for your pool, it is understandable to get confused. This is why it is best to research every option and select a pool system that fits your lifestyle and household needs.

Even though the main aim of every pool system is to keep the pool water healthy and safe to swim in, each option offers different features. While one water option may require more maintenance, another may cost you more but require less on the upkeep costs.

In this blog, we have rounded up the three main water systems for your above-ground and in-ground swimming pools. Let’s dive in!

Chlorine Water System

The chlorine water system is one of the most popularly used and oldest water systems for private and public pools for decades. The reason behind its popularity is its ability to treat pool water through a chemical reaction. During this chemical reaction, chlorine breaks down into two main compounds – hypochlorous acid and hypochlorite ions which kill bacteria. Any contaminants in the water such as sun lotion, sweat, urine or dirt get killed with a chlorine water system.


Chlorine is available in liquid, granular and tablet form. It is easy to store for a long time without its effect wearing off. It is cost-effective and can be purchased in bulk easily.


Chlorine-based water systems require a lot of maintenance. Due to its unpredictable nature, chlorine can react extremely with contaminants in the water. If stored improperly, it can pose a danger to your health. If there is too much chlorine in the water, it can also cause irritation of the eyes and the skin. Plus, it can leave a lingering pool odor which can be a big turn off.

Saltwater Systems

Saltwater pools are an excellent alternative to chlorine-based water systems. They go back to the 1980s and are still preferred by many pool owners. When you choose a saltwater system for your pool, instead of adding chlorine, you will need to add salt. The salt you add produces low levels of chlorine through a process called “electrolysis”. In this process, the salt breaks down into chloride ions and sodium ions. The chloride ions convert into chlorine when a low voltage electrical current is passed through the water.


The prime advantage of investing in a saltwater system is its lower maintenance compared to chlorine-based water systems. Plus, the water feels softer and there are no side effects such as damaged hair or irritation of the skin/eyes.


A major drawback of saltwater systems is that compared to chlorine water systems they can corrode your pool equipment much faster. Salt is a corrosive substance. When you introduce too much of it into your pool, it can cause the pool to decompose quickly. Lastly, saltwater systems are costlier than chlorine-based water systems.

Mineral Water Systems

As the world is increasingly becoming more health-conscious, the pool industry is also keeping pace by introducing next-level solutions that keep your health at the forefront. Enter mineral pools. They have been climbing the popularity charts because of their health benefits. One great example is the Magna Pools for in-ground as well as above ground pools.


Magnesium helps improve the water quality drastically and is gentle on your skin. Magna Pools are known for their high concentrations of magnesium which makes your skin feel silky and soft. Other water systems namely salt water and chlorine are known to dry your skin and hair. So, pool owners are turning to Magna Pools for their higher quality of water which is less harsh on the body.


The biggest complaint most pool owners seem to have with mineral water systems is having to use chlorine with them. A normal chlorinated pool has free chlorine in the range of 1.0 and 3.0 PPM. A mineral water system should not have more than 0.5 PPM. Anything lower than 1.0 PPM is close to an algae bloom. Magna Pool owners may not be able to reap the full benefits as compared to those who can keep the chlorine levels where they are supposed to be.

When Should I Fill or Refill My Pool?

Depending on your pool maintenance habits and the water quality of your pool, you should drain, clean and refill it after every 2 to 3 years approximately. However, please note that every pool may need an occasional top-up as the water levels can lower due to varied reasons. From evaporation and splash-out to backwashing, there are several factors that can lower your pool’s water level daily. Pay attention to this carefully so you know when the next top-up is due.

How to Lower Water Loss in A Pool?

If you notice that your pool’s water level is lowering at a faster rate and it is requiring top-ups sooner, your pool may have a leak. Here are some steps you can follow to conserve water in your pool:

Reduce Splashing

Every time you get out of the pool, you carry water on your body, hair, and swimsuit. Other activities such as playing and diving in the pool water contribute to more water splash outs. Not to forget, water features such as fountains and waterfalls may also cause splash out. To reduce this, keep your water levels a bit low so when you get out of the pool or dive, it doesn’t spill out from the sides. Additionally, check the direction and spray force of the waterfalls and fountains. Keep them flowing back into the pool.

Control Evaporation

Daily evaporation can take away ¼ to ½ inch of water in an uncovered pool. You can lower the evaporation rate by using landscaping to protect your pool’s surface from the wind. Consider lowering the temperature of the heating systems. Lastly, keep your pool covered when you are not using it.

Mind the Backwash

Your pool’s filter system requires regular backwashing to keep it clean. Depending on the pool filter you have, the frequency may vary. Even though this cleaning is necessary for your pool to function optimally, consider backwashing for only as much as required. The second the water runs clear you should stop backwashing. Keep your pool water balanced so there is a lesser strain on the filtration system. When you regularly maintain the pool, it will require lesser backwashing. Pick out the large debris and leaf litter using manual telescopic poles whenever you have some extra time in your hands. This will put less pressure and strain on the filter.
