POOL CARE GUIDE

Start-Up Procedure

Once your Quartzon surface has been installed, it is imperative that your pool builder follow the correct start up procedure to ensure your pool water is balanced and your Quartzon surface looks its best.

Step by Step Videos

Our series of 7 short videos explains step by step the start-up procedures and ongoing care for your new Quartzon Pool.

Ongoing Pool Care – Quartzon Cal-Stop

Like all concrete pools, your Quartzon pool may be prone to calcium scale. We therefore recommend the addition of a specially formulated polymer called Cal-Stop to your pool water every six months to keep calcium scale at bay.

Cal-Stop is a preventative measure to stop calcium scale from forming and is also useful for inhibiting scale from forming on the cells of saltwater chlorinators.

To order your bottle of Cal-Stop please fill in our on-line order form or call  1800 077 744 to place an order. Alternatively, call us for your local stockist.

FAQs – Caring for your Quartzon Pool

Calcium Scale

Why has the pool surface become patchy/blotchy?

This can be due to the high pH level causing the calcium in the water to precipitate out of solution and plate onto the surface. It can also be due to calcium levels being out of recommended limits or a higher water temperature.

Why has pool surface become sharp or abrasive to touch?

This can be due to the high pH level causing the calcium in the water to precipitate out of solution and plate onto the surface. It can also be due to calcium levels being out of recommended limits or a higher water temperature.

Why is chlorine in pool no longer removing algae?

Occasionally, despite the correct level of chlorine being present on testing, algae may have developed. This may be because the levels fluctuated previously or there is poor water circulation due to inferior pool design. When water circulation is poor algae spores are protected by stale/dead water on the surface. As soon as there is a drop in the free chlorine level, algae growth will accelerate.

How to remove patchiness and blotchiness on pool surface

If scale hasn’t been on the surface for too long, lower the pH to between 6.5 and 6.8 (using hydrochloric acid). Leave at this level for approximately 1 week and brush the affected areas over the duration to remove the scale. Take a water test and balance accordingly. Monitor the surface texture of the pool daily. If the surface becomes rough over exposure may occur. To prevent over exposure, increase the pH with pH Increaser as soon as excessive roughness is detected.

 

After performing this procedure, it is imperative that calcium levels in the water are returned to recommended levels (200-250ppm).  Failure to do so could cause excessive acid demand which inturn will weaken the surface and may lead to other problems.

If scale has been on the surface for a number of months then the pool will most likely have to be drained and acid washed, then filled up and re-balanced.
Experienced pool technicians may add acid (10-15L for average 50,000L pool) to the pool the day before it’s drained to soften the calcium.  The pool is then drained and using a high-pressure cleaner, the calcium is water blasted off.  The pool is then refilled and rebalanced.

To avoid future calcium scale occurrences, maintain Cal-Stop in your pool water.  This can be achieved by purchasing a bottle of Cal-Stop from your local pool shop every 6 months.  Cal-Stop keeps calcium in solution even if the pH level does increase.  If your local pool shop doesn’t stock Cal-stop then please order online here.

How to remove sharp abrasive texture off pool surface?

Leave at this level for approximately 1 week and brush the affected areas over the duration to remove the scale. Take a water test and balance accordingly.

Sharp abrasive texture on pool surface for over three months, how to remove?

If scale has been on the surface for a number of months then the pool will most likely have to be drained and acid washed, then filled up and re-balanced.  Experienced pool technicians may add acid (10-15L for average 50,000L pool) to the pool the day before it’s drained to soften the calcium.  The pool is then drained and using a high-pressure cleaner, the calcium is water blasted off.  The pool is then refilled and rebalanced.

Inconsistent Colour (walls to floor)

Why is the floor of pool a different colour to the walls?
This can be due to over exposure of the floor, too much time left between finishing walls and beginning the floor, or the floor was trowelled at ninety degrees to the direction the wall was trowelled.
How to correct pool surface so floor and wall colour are the same?
You should contact your experienced pool contractor to complete the below task.
Acid wash the pool again applying particular attention to blending in the floor to the walls.

  • It may be possible to expose more of the coloured aggregate in the walls thereby darkening them and providing a better match, and/or;
  • Polishing the joint line and the floor. Polishing slightly lightens the surface as glaze is removed from the coloured aggregate.

After performing either of these procedures it pays to pressure wash the entire surface, as this will remove excess oxide. Doing so helps to even out colour variations.
Whilst it may not be possible to completely eliminate all the colour variation, the solution described above will certainly help. Over time the discrepancy will reduce of its own accord as the cement sits immersed in water and fully hydrates.

How to prevent colour variation on floors & walls when acid washing

Pay particular attention when acid washing to make sure acid is not allowed to sit on the floor of the pool. Ensure that a wet edge is maintained at all times.
Also consider:

  • Ensuring adequate trowel hands are available.
  • Reducing the length of the wet edge by working across the pool rather than doing the walls first then the floor.
  • Avoiding cross trowelling at joins, i.e. when joining the walls to the floor, attempt to trowel the floor in the same direction as the walls.
  • Ensure batches of stock are mixed evenly from different production dates.
How to control depth of pool surface when acid washing?
Pay particular attention when acid washing that acid is not allowed to sit on the floor of the pool. Ensure that a wet edge is maintained at all times.

Rough Spots

Why are area/s of pool surface rough to touch?
If the area is darker, it may have been overexposed. The acid may have been left too long when exposing or maintenance procedures have been poor.
What is the cause of rough areas on pool surface that resemble streaks and appear to flow downwards?
If in patches, the area/s usually look slightly darker in colour when compared to the rest of the surface. Darker areas have been overexposed which can be a result of:

  • Acid being left too long on the surface during the acid wash/acid bath causing an excess of cement to be washed away which leaves remaining aggregate protruding from cement (over exposure of aggregate).
  • Acid must always be diluted when added to pool water. If it’s not and is added to pool water, the acid will sink to the bottom and overexpose the surface (acid is heavier than water).

Note: If rough patches are lighter or dull in colour, refer to Calcium Scale questions.

How to repair areas on pool surface that are overexposed?
Areas of overexposure need to be sanded down using either wet and dry sandpaper or a rubbing stone. Be careful not to over rub the spot causing a lightening of the surface. Make sure to test first on a small unobtrusive area.

Ensure that any acid to be added to the pool is always diluted.
