How to clean a quartz finish pool
A sand pool is not cleaned very differently from any other. What changes is which brush you use and how much balanced water matters. This is the routine we recommend to owners of a pool finished in quartz aggregate.
How do you clean a sand pool?
With a nylon-bristle brush —never a metal one—, a pool cleaner or robot, empty skimmer baskets and a pH between 7.2 and 7.6. That keeps the finish's colour and texture for years. It does not need special products.
The weekly routine
- Empty the skimmer and pump baskets. Leaves left there dirty the water and reduce the flow to the filter.
- Brush the walls, steps and beach. With a nylon or polypropylene brush. Brush the beach and shallow areas more often: they warm up sooner and that is where dirt settles.
- Run the pool cleaner or robot. Robots are fine to use; choose one with rubber or foam brushes, not stiff bristles.
- Test the pH and sanitiser, and adjust. This is the step that does most to extend the life of any finish. More on it below.
- Check the filter pressure. When it rises above normal, it is time to backwash.
Balanced water is what makes the finish last
Badly unbalanced water attacks any finish, whether quartz aggregate, mosaic tile or paint. The worst offenders are a low pH kept for a long time and too much chlorine. What to keep an eye on:
- pH between 7.2 and 7.6. It has the biggest effect and is the easiest to test.
- Sanitiser within range, without unnecessary shock doses.
- Alkalinity and hardness within the recommended values. Any pool shop will test a water sample for you.
It works just as well with salt chlorination: salt on its own does not harm the finish. What harms it is an uncontrolled pH, whatever the system.
How do you clean sand off the bottom of a pool?
If it is loose sand that came in from the garden or on people's feet, with the pool cleaner or robot, like any other dirt. If you mean the finish itself, that is not loose sand: it is quartz aggregate bound with cement and polymers, and cleaning does not remove it.
The first days after application
It is normal for a newly applied finish to shed some aggregate, especially at first. It is not a defect. In those first days, brush and run the cleaner more often, following the applicator's instructions, since they know how that particular job is curing.
What not to do
- Metal brushes or steel bristles. They scratch any finish.
- Pouring concentrated products straight onto the finish. They are dissolved and spread through the water, not tipped onto one spot of the floor.
- Leaving the pH low for weeks because "the water looks fine". The damage does not show until it is done.
- Draining the pool without a reason. If you think it needs draining, ask first.
Can you use a cover on a sand pool?
Yes. Winter covers, solar covers and automatic covers are used just as on any other pool, and they help: fewer leaves, less evaporation and fewer chemicals.
In winter, keep the water balanced even when nobody swims. It is when pH is most often neglected, and it shows later.
How often does the quartz in a pool need replacing?
It is not replaced like filter sand. The quartz aggregate is part of the finish, which is mineral, bonds with the concrete and is highly durable: there is no liner to replace and no paint to redo every few seasons. If you mean the sand or glass media in the filter, that is a different thing and depends on the filter manufacturer.
