Why Keeping Your Pool Water Clear Matters

As a New Zealand homeowner, there’s nothing more satisfying than looking out at a sparkling, crystal-clear swimming pool – especially when summer is in full swing. But maintaining that perfect water clarity takes a bit of effort. Without regular care, algae, debris, and chemical imbalances can turn your inviting pool into a cloudy mess.

So, how do you keep your pool water clean and clear all year round? Here’s a straightforward guide with useful tips and resources from trusted New Zealand retailers and experts.

Regular Cleaning & Maintenance

1. Skimming & Vacuuming

Leaves, dirt, and debris can quickly build up in your pool, leading to murky water and clogged filters. To prevent this:

• Skim the pool surface daily – A simple pool skimmer net will remove floating debris before it sinks and causes further problems.
• Vacuum the pool weekly – Automatic pool cleaners from Pool & Spa Warehouse are a great option for keeping the floor and walls clean with minimal effort.

2. Brushing the Walls & Tiles

Over time, algae and calcium deposits can form on pool walls and tiles, making the pool look dull and affecting water chemistry. Use a pool brush to scrub the walls and steps at least once a week.

Balancing Pool Chemicals

For a healthy swimming environment, it’s essential to test and balance the pool water regularly. You can pick up a pool test kit from stores like Para Rubber or have your water tested at a local pool shop.

Key chemical levels to monitor include:

• pH Level (7.2–7.6) – If the pH is too high or too low, it can cause eye irritation and make chlorine less effective.
• Chlorine (1–3 ppm) – This is the primary disinfectant that kills bacteria and algae. Shock the pool occasionally to maintain water clarity.
• Alkalinity (80–120 ppm) – Helps stabilise the pH and prevents sudden changes in water chemistry.
• Calcium Hardness (200–400 ppm) – Prevents damage to pool surfaces caused by soft or hard water conditions.

The team at Swimart offer free water testing and advice if you’re unsure about your pool’s chemical balance.

Optimising Filtration

The pool filter plays a huge role in keeping water clear by trapping dirt and debris. Make sure you:

• Run the filter system for 6–8 hours a day – This keeps water circulating and prevents algae growth.
• Backwash sand or DE filters regularly – If you have a cartridge filter, clean it every few weeks.
• Check for blockages in skimmer and pump baskets – Clear out leaves and debris that might restrict water flow.

Preventing & Treating Algae

Algae thrive in warm water, especially if chemical levels are off. To prevent algae growth:

• Maintain proper chlorine levels – This is the first line of defence.
• Use an algaecide as a preventative measure – Products from BioGuard NZ can help stop algae before it starts.
• Brush pool walls and steps weekly – This removes potential algae spores before they spread.

If you’re dealing with a green pool, you may need to “shock” the water with a high dose of chlorine and use a clarifier to help the filter remove dead algae particles.

Rain & Environmental Factors

In New Zealand, weather can change rapidly, affecting your pool water clarity. After heavy rain:

• Test and rebalance chemicals – Rainwater can dilute chlorine and alter pH levels.
• Remove debris – Storms can bring in leaves, dirt, and even small critters.
• Use a pool cover – This reduces evaporation and keeps out unwanted debris. Mr Pool Man NZ stocks a range of pool covers to suit different pool sizes.

Professional Help When Needed

Even with regular maintenance, sometimes water clarity issues can be stubborn. Don’t hesitate to call in a professional pool service from companies like Poolmart NZ if you need expert help troubleshooting persistent water problems.

By keeping up with regular cleaning, maintaining proper chemical levels, and ensuring good water circulation, you’ll enjoy a beautifully clear pool all year round – ready for those hot New Zealand summers!
