Frequently Asked Questions

Fibreglass pool shells are durable and can flex without cracking to accommodate earth movement.

They are cost effective, and quick to install. Your pool can be ready and installed as early as 2 -3 weeks after confirmation of order. Their finish is smooth, non-abrasive, and they have no sharp edges, making them safe for the whole family.

Moreover, fibreglass pools are hassle-free and easy to maintain. Their nonporous shell is not conducive to algae growth, and the amount of sanitizing chemicals required to maintain the pool is much lower than for concrete pools.

Remember that an in-ground pool is a permanent structure, and will be a prominent feature in your yard for years to come. Here are a few tips to help you select your ideal pool:

1. Define how you will use your pool.

Why are you installing a swimming pool: Is it for relaxation? For your kids? For entertaining? Is it an investment?

Defining the uses will help you choose the best location for your pool and decide on the style that meets your needs. In general, rectangular designs are perfect for people looking for a classic look, and are great for swimming laps. Kidney and free-form swimming pools blend with the surrounding vegetation and appear more natural.

2. Choose the finishing touches.

Think about which material you would like to use to pave your pool deck: concrete, tiles, wood… Factors to keep in mind at this stage include the cost, slip resistance, upkeep, durability, and how well it complements the surroundings.

3. Consider the financial implications of maintenance

Routine pool maintenance will include keeping the water chemically balanced and sanitary, maintaining the support equipment, and cleaning the pool surfaces. And of course, the bigger the pool, the higher the cost.

4. Think about pool security

Consider what other safety measures you will be needing. If you have young children, safety nets or fences are strongly recommended.

In order to remain clear and clean, swimming pool water must undergo treatment. There are 3 main water treatment options: chlorine, salt and magnesium.

Chlorine

Chlorine is the most frequently used water treatment method. It dissolves into your pool water, and destroys a wide range of potentially dangerous bacteria and harmful contaminants.

This water treatment method is however time consuming, as chlorine must be added manually to your pool water on an ongoing basis.

Salt

Salt chlorinators produce a powerful and effective disinfectant from the electrolysis of salt water.

Sodium Chloride, common salt, is added to the pool water, and is transformed into chlorine gas that dissolves into the water. This is what keeps the water clean.

Magnesium

Magnesium chlorinators create a natural disinfectant from magnesium and magnesium hydroxide.

This economical and eco-friendly system requires very low mineral content to be added at the start and every new season.

Salt and magnesium chlorinators are more expensive upfront, but allow a quick return on investment because of reduced running costs.

A ‘balanced’ swimming pool is a pool that keeps the basic pool water components (pH, total alkalinity, calcium hardness and stabilizer) within their proper levels.


A proper pH level is in the range of 6.8 to 7.2 for a fibreglass pool & 7.2 to 7.6 for a concrete pool. Low pH readings mean your chlorine will dissipate a lot quicker. High pH levels make chlorine inactive.

Total alkalinity refers to how much alkaline is in the pool water. Low alkaline water leads to low pH and high alkaline water leads to high pH. Your pool water should have a total alkalinity level of 125 – 170 ppm.

The general range for calcium hardness levels is 200 to 400 ppm. When calcium hardness is too low, pool corrosion can occur. If levels are too high, scale deposits and cloudy water can become a problem.

Stabilizer is important because it helps retain pool chlorine longer. Stabilizer has a 40 to 100 ppm ideal range. If your stabilizer level is low, you will use a lot more chlorine.


To maintain balance water, use a good test kit to measure the chemical parameters of pH, alkalinity, calcium hardness and stabilizer. If your pH level is low, you should add sodium carbonate (pH Up) to bring it up. If it is too high, you should add acid (pH Down) to bring down the pH.

Sand: Each 2 – 3 years

Clinobrite: Can be regenerated each year and renewed each 3 – 4 years.

To keep your pool water clean and healthy, test the water at two ends or sides of the pool a minimum of twice a week.

You can monitor your pool’s water with a testing kit. There are basically two types of swimming pool water testing kits: reagent kits and test-strips.

When using reagent kits, you will be required to take a sample of pool water, then add liquids or tablets to it. The water will change color, indicating its chemical balance.

Test-strips must be submerged in the pool for a few seconds, and the dyes they contain will cause them to change color. The strip should then be mapped to a color chart to determine the pool’s water balance.

Sometimes it’s difficult to determine if low water levels are due to evaporation, splash-outs or a leak. Generally speaking, if you routinely add more than 5 cm of water to your pool per week, you may have a leak.

A pool can leak through its plumbing, its fittings, its accessories, or even through the shell. Here are a few questions that may help you to locate the leak:

• Is the pool leaking only with the equipment on? This may indicate a leak on the pressure-side of your plumbing, somewhere past the impeller of the pump.
• Is the pool leaking only with the equipment off? This usually indicates a suction-side leak, somewhere before the impeller of the pump.
• Does the pool leak all the time? In this case the leak may be found in the pool’s shell.
• Are there leaks at the equipment pad? Moist ground or spraying water when the pump is turned off may indicate a problem with your equipment pad.
• Does the leak seem to stop past a particular level? Close the skimmer valve and allow the water level to drop below the skimmer. If water level stabilizes, turn a suspicious eye on the skimmer.
