Common Pool Problems & Expert Solutions

Frequently asked questions

Why is my pool water cloudy or green?

Cloudy or discoloured water is usually caused by poor filtration or chemical imbalance.
Check your pH and chlorine levels first — low chlorine or high alkalinity allows algae to grow.
If your filtration system is working but clarity doesn’t improve, your filter media may need cleaning or replacement.

What causes stains or discolouration on pool surfaces?

Pool stains often come from metal or mineral deposits in the water or from organic material like leaves and algae.
Regular brushing, balanced pH, and professional water testing help prevent staining.
For stubborn marks, we can provide professional liner or surface cleaning services.
See our Pool Liner Replacement page for surface restoration options.

How do I know if my pool has a leak?

A drop in water level could be evaporation — or a leak in your liner, fittings, or plumbing.
Perform a simple bucket test (compare water loss in a bucket to the pool over 24 hours).
If the pool level falls faster than the bucket, you likely have a leak that needs professional assessment.
Book a check through our Pool Care & Maintenance team.

Why isn’t my pool pump working efficiently?

Reduced flow, noise, or air bubbles usually point to blockages, a worn seal, or an air leak in the system.
Regular servicing prevents these issues and keeps energy use low.

What’s the best way to prevent recurring problems?

Consistent maintenance is key — clear filters, correct chemical balance, and seasonal checks prevent most pool issues.
Many pool owners choose a regular maintenance plan for peace of mind and better water quality year-round.

Can I fix these issues myself?

Minor problems like basic pH imbalance can be corrected with test kits and proper dosing, but for leaks, equipment faults, or recurring cloudy water, professional intervention saves time and money.

Hydro-Leisure Plus technicians use advanced testing and diagnostic tools to resolve the root cause safely and efficiently.

Can structural issues cause recurring pool problems?

Yes — cracks, movement, or poor construction can lead to ongoing leaks, uneven surfaces, or water loss.
If your pool is showing repeated issues even after repairs, it may be due to its underlying structure.
Our team can assess your pool’s build and recommend the best long-term solution.
Learn more about build methods on our Pool Construction page.

When should I replace or upgrade my pool liner?

If your liner is faded, brittle, or showing signs of leaks or wrinkles, replacement is often the most effective solution.
A new liner not only improves appearance but also protects against water loss and further damage.
