Practical answer
In strong Cyprus sun, stabilizer and pump run time matter because chlorine effectiveness and filtration time decide whether the water actually clears.
What to check first
- Take fresh chlorine, pH, and stabilizer/CYA readings if possible.
- Check whether the filter pressure is normal, high, or unusually low.
- Look at whether the cloudiness is uniform, settled on the floor, or returning after brushing.
- Confirm the pump is running long enough for summer conditions and heavy use.
What not to assume
- Do not keep shocking without knowing CYA/stabilizer and pH context.
- Do not backwash so often that the filter never works efficiently.
- Do not confuse settled dust with active algae without brushing or vacuuming checks.
When this needs more than a quick check
Collect more detail or request help if:
- the water is green, cloudy, or unsafe to inspect clearly
- the pump is noisy, leaking, tripping power, or losing prime
- guests are arriving soon and the pool needs time-sensitive assessment
- you are not sure which chemicals were already added
Details to collect before requesting help
- photos of the whole pool and the water close up
- photos of the pump, filter, skimmer, and equipment labels
- pool size, area in Cyprus, and guest-arrival deadline if relevant
- recent test readings or a photo of the test strip
