Most homeowners measure water treatment cost by the price of chlorine and tablets, and when they want to save, the first thing they cut is regular testing and careful adjustment. The trouble is that unbalanced water can look clear and inviting while it quietly eats grout, lays scale on the walls or corrodes the handrail. That is the hidden cost: damage that builds silently and then appears all at once as a renovation job. This article shows where that cost hides and how a simple routine catches it early.
Water balance basics without the jargon
- pH: the accepted range is about 7.2 to 7.6. Below it, water turns acidic and attacks surfaces. Above it, scale forms and chlorine works poorly.
- Free chlorine: the part that actually sanitises. Too little lets bacteria and algae grow, too much irritates eyes and skin.
- Total alkalinity: a buffer that stops pH from swinging quickly.
- Calcium hardness: too low and water pulls calcium from plaster and grout, too high and it deposits scale.
In a climate like Riyadh, heat and sun burn through chlorine fast, and high evaporation concentrates salts and minerals over time. Water changes faster than most people expect, and infrequent testing cannot keep up.
Top up water matters too. When water evaporates, it leaves its minerals behind, and the fresh water you add brings more. Over a long summer, salts and calcium creep upward until the water leans toward scaling. That is why some pools eventually need a partial water change rather than more chemicals. Wind blown dust, leaves, sweat and sun cream all add organic load that consumes chlorine as well.
What routine treatment costs look like
Regular treatment has clear, predictable expenses: a test kit or strips, chlorine in the form your system uses, pH adjusters and an occasional shock treatment after heavy use or a dust storm. This spending is steady and easy to plan. Balanced water also needs fewer chemicals than people expect. The heaviest chemical use happens in pools that are neglected and then rescued in a hurry.
Where the hidden cost sits
Tiles and grout
Acidic water slowly dissolves grout. Joints sink and roughen, water gets behind tiles and they start to loosen, which can lead to regrouting or retiling whole areas.
Plaster and cement finishes
Acidic or low calcium water etches cement surfaces, leaving rough patches and pits that hold algae.
Scale
High pH with hard water leaves a white line at the waterline and scale inside pipes and heaters, cutting efficiency and raising running costs.
Metal fittings
Ladders, handrails, light rings and screws corrode faster, and some metals leave stains on tiles that are hard to remove.
Filter and pump
Algae and deposits clog the filter sooner and strain the pump, as explained in our article on filter replacement after neglect.
The health side
More important than any repair is the effect of poorly treated water on your family. Low free chlorine allows bacteria that can cause ear, skin or eye infections, especially in children who spend long periods in the water and swallow some of it. Excess chlorine or poorly controlled pH causes red eyes, dry skin and breathing irritation for some swimmers. Clear water is not proof of safe water. Testing is the only way to know.
Quick comparison
| Area | Regular treatment | Neglected treatment |
|---|---|---|
| Chemicals | Small, steady amounts | Repeated shock doses and large quantities |
| Tiles and grout | Stay in good condition | Erosion, loosening, renewal needed |
| Metal | Very slow wear | Rust, stains, early replacement |
| Equipment | Stable efficiency | Scale, clogging and faults |
| Pool use | Available any time | Frequent closures for treatment |
Suggested water testing routine
- At least twice a week in summer: test free chlorine and pH, weekly in cooler months.
- After heavy use or dust storms: test again and adjust straight away.
- Periodically: check alkalinity and hardness, which change slowly but affect everything.
- Keep a log: a notebook or phone note shows trends before they become problems.
- Call a professional if you see discolouration, a white waterline, rough grout or repeated irritation among swimmers.

Frequently asked questions
If the water is clear, is it balanced?
Not always. Water can look clear while pH or chlorine is outside the right range. A test kit or strips are the only way to be sure.
What is the right pH for pool water?
The accepted range is about 7.2 to 7.6. Within it chlorine works efficiently and the water is comfortable for eyes and skin and gentle on surfaces.
Why has my grout become rough and sunken?
Usually from long periods of acidic or low calcium water that slowly dissolves the grout. Balance the water first, then assess and renew the joints if needed.
Does summer heat affect water chemistry?
Yes. Sun and heat consume chlorine faster and evaporation concentrates salts over time, so testing should be more frequent in summer.
