Frequently asked questions

To help you understand the many aspects of swimming pool care & maintenance we have compiled a list of the questions most commonly asked by our customers.

Of course, if you have a question about your pool or spa not covered in the list below, don’t hesitate to call or email us!

What is pool automation?2018-04-03T12:41:31+08:00

Automation gives you push-button control over pool and spa operation and heater and blower control, either with a hand-held remote control or from an in-house wall-mounted panel. No more walking out to the pool equipment to turn on heater or spa operation! You can also control these and other operations from your computer, tablet, or cell phone.

What is chlorine stabiliser?2018-04-03T12:45:00+08:00

Chlorine stabiliser is an organic compound that protects chlorinating products from the sun. It is also known as cyanuric acid and is sometimes referred to as “conditioner.” Water that is stabilised offers pool owners a definite advantage over unstabilised pools. For instance, for every 35 minutes that a pool is exposed to the sun, the water will lose half of its HOCI (the hypochlorous acid that forms when chlorine is dissolved in water and that is responsible for the disinfecting power of chlorine.)

What is a salt pool or a salt-water chlorinator?2018-04-03T12:42:07+08:00

Salt-water chlorination is a process that uses dissolved salt (2,500–6,000 ppm) as a store for the pool’s chlorination system. The chlorine generator (also known as a salt cell, salt generator, or salt chlorinator) uses electrolysis in the presence of dissolved salt, or sodium chloride (NaCl), to produce hypochlorous acid (HCIO) and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools. As such, a saltwater pool is not actually chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine.

What is “Total Alkalinity”?2018-04-03T12:46:00+08:00

Total Alkalinity (TA) is a measure of water’s resistance to changes in pH levels. A pool’s TA indicates the amount of alkali (not to be confused with alkaline) in the form of bicarbonates, carbonates, and hydroxides present in the pool water. A proper TA level helps to control pH bounce, staining of surfaces, and corrosion of pool equipment.

Automation takes the work out of pool and spa ownership by automating all work-intensive functions, such as sanitisation, balancing of pH, cleaning, and filtration. There are many systems available, some of which you can control from your phone.

What are phosphates?2018-04-03T12:57:24+08:00

Phosphate is the major cause of algae in swimming pools. Phosphate and nutrients are required by all living organisms — including algae — to survive and flourish. Phosphate is introduced to pool water from a variety of sources, including rain, runoff from lawns and gardens, fertilizers, birdseed, plant material, dust, suntan oil, and leaves. In time, all of these sources will cause a buildup and increase the concentration of phosphate in the water and thus promote progressive algae growth. There are phosphate removers available to reduce the level of phosphate in your swimming pool water below 100 ppm (ideally, you want it as close to a zero reading as possible).

How long should my filter run each day?2018-04-03T12:49:18+08:00

Your pool filter is the single most important component in keeping your swimming pool clean. Ideally, a filter should run all the time for maximum circulation and debris removal. A minimum of 8 hours a day in summer and 4 to 6 hours per day in the winter is highly recommended.

Do I need to brush my pool regularly?2018-04-03T12:47:10+08:00

Yes. Dirt, pollen, and algae will naturally collect in all the crevices of your pool, so use a pool brush to break it up. Regular churning of the water (from brushing or swimming) will give the filter an opportunity to suck up the debris before it settles.

How can I tell if my pool is leaking?2018-04-03T12:56:24+08:00

Normally, pool water evaporation is about 1″ to 2½″ per week. To determine if you have a leak, you can perform a simple bucket test using an ordinary plastic bucket:

  1. Bring pool water to normal level (middle of skimmer).
  2. Place a bucket on the first or second step of the pool.
  3. Fill the bucket with pool water to the same level as the pool.
  4. Mark the water level on the inside of the bucket.
  5. Shut off the pump and mark the pool water level on the outside of the bucket.
  6. Resume normal pump operation.
  7. After 24 to 48 hours, compare the two water levels:
    • If the pool water level (outside mark) goes down more than the water level inside the bucket, you probably have a leak.
    • In case of rain, repeat the test (be sure that your pool is equipped with an auto-fill to shut off the water supply).

Test is invalid after 48 hours.

Why does my pool have stuff floating on top?2018-04-03T12:55:48+08:00

Make sure there is a weir (a floating flap) at the entrance to your skimmer. Make sure your water level is about halfway up the skimmer. The debris that floats should go into the skimmer as the water circulates. The weir and water level are important for this to happen.

Why does my pool have a ring of scum at the tile?2018-04-03T12:55:17+08:00

Floating oils, dirt, and waste can combine to form a scum line around the pool; this is why tile, an easily cleanable surface, is placed at water level around the perimeter of the pool. There are many tile cleanser products available that may be applied with a scrubbing pad or brush and a little elbow grease.

How do I add water to my spa/pool?2018-04-03T12:52:21+08:00

You can purchase an auto-fill float valve or a hose timer. You can also just use a garden hose from home hose bib. It is important that your pool maintain the correct volume of water for the equipment to function. If the water level gets too low, the pump will start sucking up air instead of fluid, the motor will overheat, and parts will melt. This will require replacement of equipment.

What is the white, hard material that is on my tile?2018-04-03T12:53:44+08:00

That is called efflorescence, and it comes from the grout. This unsightly buildup can be removed with special products. It is not a problem caused by the pool chemistry.

What are those stains on my pool, and how do I get rid of them?2018-04-03T12:54:41+08:00

Below are a few of the most common materials that lead to surface stains on the pool walls and floor. Their exact effects are always influenced by the water’s overall pH, oxidation-reduction potential, calcium hardness, total alkalinity, and saturation index.

  1. Iron (Fe)
    • Origins: Fill water, degraded pipes or equipment, impurities in salt.
    • Evidence: Green water; cloudy yellow, red, or brown water or surface stains.
    • Treatment: Sequestering or chelating agent; gentle brushing, or chlorine/acid wash for more severe stains.
  2. Copper (Cu)
    • Origins: Fill water, degraded pipes or equipment, copper algaecides, impurities in salt.
    • Evidence: Green, blue-green, yellow, brown, gray, or black color in water or plaster.
    • Treatment: Sequestering or chelating agent; gentle brushing, or chlorine/acid wash for more severe stains.
  3. Manganese (Mn)
    • Origins: Fill water, impurities in salt.
    • Evidence: Gray, black, lavender, or purple color in water or plaster.
    • Treatment:
      1. Sequestering or chelating agent; gentle brushing, or chlorine/acid wash for more severe stains or gray deposits on plaster.
      2. Gentle brushing, or acid wash for tougher deposits; balance pH and calcium hardness.
  4. Fertilizer Stains
    • Origins: Fertilizer pellets that get into the water will drop to the floor of the pool. These pellets contain iron and other minerals, which then stain the pool.
    • Evidence: Brown spots.
    • Treatment: These stains will go away on their own if the pool water is balanced properly.
  5. Leaf Stains
    • Origins: Leaves that have fallen into the pool and are not promptly removed.
    • Evidence: Brown stains where leaves have accumulated.
    • Treatment: These stains will go away on their own with elevated free chlorine in the water.
