Most home pools are built for the family, so children can play and stay active in summer instead of sitting in front of screens. The same pool can become a source of worry when maintenance slips. Water that looks clear is not always safe, and fittings that were sound a year ago can cause an injury today. Children are especially exposed: they swallow more water, stay in longer, have more sensitive skin and notice danger less than adults. This article explains the health and physical risks a neglected pool can pose, how to tell when your pool needs attention and the simple habits that protect your household.
Health problems linked to poorly treated water
- Skin irritation and rashes: redness and itching after swimming, sometimes small bumps where wet swimwear stays against the skin.
- Red, stinging eyes: often blamed on too much chlorine, but usually caused by unbalanced pH or spent chlorine compounds formed from sweat and dirt.
- Outer ear infections: contaminated water left in the ear creates conditions for infection, common in children who dive a lot.
- Stomach upsets: children often swallow water, and contaminated water can cause diarrhoea or cramps.
- Respiratory irritation: in covered or poorly ventilated pools, fumes from spent chlorine can bother people with allergies or asthma.
Why clear water is not always safe
Clarity comes from the filter. Safety comes from sanitising and balance. The filter can make water look clean while active chlorine is very low because of sun and heavy use. Chlorine may also be present while high pH weakens it. Testing is the only way to know, not appearance or smell. A strong chlorine smell, which people link to excess chlorine, usually signals the opposite: spent chlorine and water that needs treatment.
The key readings are free chlorine and pH, with pH at about 7.2 to 7.6. Readings far from normal mean the water needs correcting before anyone swims.
Physical hazards caused by neglect
- Slips: algae on steps and wet decks makes surfaces very slippery, and a fall against the pool edge can cause a head injury.
- Cloudy water: when you cannot see the floor, you cannot see whether a child has gone under and not come back up, one of the most dangerous situations in any pool.
- Broken or missing drain covers: suction at the drain can trap hair or limbs. An intact, properly fixed cover prevents this.
- Broken tiles and sharp edges cut feet and hands, and open cuts in unsanitised water can become infected.
- Corroded ladders and rails: rust weakens fixings, and a ladder that moves when climbing can cause a fall.
- Electrical faults: pool lights and equipment near water with damaged insulation or weak earthing are a shock hazard and need a qualified technician immediately.
Why children are more at risk
Children stay in the water longer, open their eyes underwater, swallow water without noticing and run on wet decks. Many play on steps and in shallow areas, the very places where algae starts. Their bodies also react faster to irritation and infection. If you have children, the pool deserves a higher level of attention: more regular testing, cleaning of shallow areas and constant supervision by an adult, however well the child swims.
Signs the pool is unsafe right now
- Cloudy or greenish water, or you cannot see the main drain.
- Slimy walls or steps.
- A very strong chlorine smell with red eyes for most swimmers.
- Foam or an oily film on the surface.
- A broken or missing drain cover, or an exposed suction opening.
- A light fitting with water inside or flickering abnormally.
- A loose ladder or broken tile on the edge.
Any one of these is reason enough to stop swimming until it is fixed.
Simple habits that protect the family
- Test the water before and after busy swimming days, and more often in summer.
- Shower before swimming to cut sweat and lotions that use up chlorine.
- Regular toilet breaks for children to reduce contamination.
- Dry ears after swimming, especially for children who dive.
- Run the filter long enough and empty skimmer and pump baskets.
- Glance over fittings: covers, ladder, edges and lights.
- Store chemicals dry, locked and out of children's reach, and never mix products.
- Constant supervision: no child swims without an attentive adult, and a fence or gate that keeps young children out without the family knowing is a wise addition.
When to ask for a professional check
If the pool has been neglected for a long time, skin and eye problems keep returning despite treatment, or you notice anything wrong with lights or electrics, ask for a full inspection covering water chemistry, filtration, fittings and electrical safety. It finds the cause rather than treating symptoms and gives you a clear plan to make the pool safe again.

Summary for parents
- Clear water is not proof of safety. Testing is.
- Red eyes and a strong smell usually mean spent chlorine.
- No swimming when the floor is not visible.
- Drain covers, ladders and electrics are part of health and safety.
- No device replaces constant supervision of children.
Frequently asked questions
Why do my children's eyes go red after swimming?
The usual cause is unbalanced pH or spent chlorine linked to sweat and dirt, not excess chlorine. Test and correct pH and free chlorine, and see a doctor if symptoms continue.
Does clear water mean the pool is safe?
No. Clarity comes from the filter, while safety depends on active chlorine and pH. Testing is the only way to be sure.
What is the biggest danger of a neglected pool for children?
Cloudy water that hides the floor, damaged drain covers, slippery surfaces and any electrical fault. These need immediate action before anyone swims.
How often should I test the water if I have children?
Regularly through the week, with extra tests in summer and before and after busy days. Consistency matters more than quantity.
